Thunder Strikes Back

Chapter 533 Magnetic Anomaly Detection

Luosang stood at the bow of the boat, staring straight ahead at the vast expanse of whiteness, with mixed feelings in his chest. It wasn't until he heard the faint sound of rotors that he realized that although the heavens showed miracles, they didn't guarantee the success of his actions.He quickly yelled and asked the adjutant Jiang Yang on the bridge to turn off the searchlight.

Thirty seconds after the lights were turned off, the sound of the rotors became clearer, and he could hear that they were a few Mi-30 helicopters flying not too high, not the attack helicopters that came and went like the wind.

In the next few minutes, the sound of the helicopter came and went, but it did not leave.Lausanne guessed that the helicopter must have seen its own lights before, but right now, they should not be able to see itself, because the sound of the rotors swirling through the air flow, every time it missed it from a hundred meters away from one side.He couldn't help secretly rejoicing that he discovered it in time, so it could be seen that the gods were still caring for him in the clouds.The enemy is probably confused again at this moment.

The lack of ships in the Chinese army is the basic fact that this plan can be implemented, which makes it difficult for them to completely monitor the ships in such a large river basin, not to mention that the Brahmaputra River may be the most complex river in the world during the dry season. A large number of rocky beaches emerge from the water, and fragmented islands lie across the river. Even with radar search, it is difficult to search for ships that are not too large in such a complicated area.He believed that the helicopter would be able to get rid of it in a short while through the thick fog.

As Luosang expected, Chang Yong really lost his target. He was already 300 meters in the air, and saw the faint shadow of the boat under the distant lights, but suddenly disappeared. Obviously, he was eager for success and was noticed by the other party.He tried to use low-light night vision and thermal imaging equipment for surveillance, but after trying one by one, he found that these methods could not find the target.The fog on the river has become the most effective protective umbrella for the enemy, seriously restricting the role of passive observation equipment.He could have dropped the EMP bomb right away, but hesitated for a while, not wanting to lose the opportunity all at once.I don't know at the moment, is this ship still below?The headquarters still kept reminding him that when the target is not named, you must not drop ammunition. There are troops along the coast here, and it will be troublesome to injure one of your own.

"Squadron leader, I reckon, maybe it was just a local armed ship? They have been moving around recently, preparing to grab territory or something." The co-pilot said, what he was most afraid of was dropping the bomb, which was thrown by a previous attack. The helicopter with the EMP bomb lost contact after dropping the bomb, and its whereabouts are still unknown.If he hadn't seen the real thing, he would never have believed that there would be a weapon in the world that does not distinguish between the enemy and the enemy and can cause equal damage.

"It is indeed possible, but we must not be careless. Immediately report our findings to our superiors. We have confirmed that there is a ship on the main channel, about 15 kilometers away from Tespur."

While stabilizing the plane, Chang Yong asked the transmitter behind him to report the discovery.Sure enough, Lin Huaisheng asked him to continue searching until he found the ship and confirmed the nature of the target.

"The visibility is too poor, and the fog on the river is too heavy." The co-pilot continued to complain.

"There is only one way for the time being. Let's go down and fly on the river. Use the front searchlight to search."

As he said, he lowered the fuselage and rushed down.Although the smog on the river was thick, it still couldn't withstand the strong wind blowing from the helicopter's rotor.All of a sudden the fog was blown away, revealing a world that could be seen ahead, but the range was not too large, but the rotatable searchlight on the nose could penetrate a certain distance for a small-scale search.

Lausanne saw a rotating light in the sky behind him from a distance, and hurried from the bow to the stern of the ship.His machine gunner was about to fight against the light, but he held it down: "Don't worry, they didn't find us."

As he spoke, he turned around and climbed onto the open-air bridge, signaling the pilot to deviate to the right and sneak away from the helicopter.

At the same time, the other three helicopters of the team followed suit, lowering their heights to search the river not far away, hoping to find some clues.

The average width of this river in the Tespur section is about 1500 meters. How can it be possible to detect it clearly with only 4 helicopters?But Lin Huaisheng had no choice but to ask Chang Yong to stay there to try his luck. Of course, fighter jets from China and an anti-submarine aircraft with special equipment are coming. They will use radar to search the river, and there may be a turning point at that time. .

Lin Huaisheng knew that radar might not be able to play much role in such a complicated river course, but if the speed of the boat was too fast, there was still a chance to identify it.Of course, he still has another method, which is to drop EMP on different river sections at the same time to destroy the enemy's detonation equipment, but this will cause a complete paralysis of our troops, especially the air defense positions along the river are likely to be destroyed, in case Lausanne finds Confucius from the air Get in, what should I do?He doesn't dare to shoulder this responsibility yet.
As a second-hand preparation, right now he was transferring troops overnight, including thousands of civilians living under curfew in Tespur City.Experts from the General Armament Department told him that if a 3-ton nuclear bomb exploded in a river instead of in the air, the effect would be greatly reduced, and the damage range might not be as ideal as the enemy expected. As long as the evacuation is timely, the casualties can be controlled to Thousands of people level.And if it's just a dirty bomb exploding on a wide river, the damage may be reduced to negligible.

The first to arrive were two Su-2 fighter jets, and they immediately began to use the radar down-looking search mode to search the river along the river.

The radar of fighter jets can naturally penetrate clouds and fog with little effort, but the standard sea search mode is not suitable in such an area. You can only use the Doppler beam sharpening mode for high-resolution mapping, but the continuous river channel The complexity of the situation is beyond imagination, a ship that is not too big and has no mast, it is difficult to be seen by the naked eye on the monitor; the first search ended in failure.After the fighter plane turned around and lowered the altitude, change the mode and use the method of filtering out the fixed terrain to search for moving targets. If there is really a moving ship, this ocean search should work.

Lobsang Gyatso heard jets whizzing past in the sky, and he was a little surprised by the alert level of the Chinese. Regardless of whether the feint troops had already taken action, it seemed that the enemy had not taken the bait, and they seemed to have guessed their plan?However, this thick fog really helped me a lot. It should be difficult for those high-altitude fighter jets to find themselves.

"Brother, there are their planes in the sky, are they coming towards us?" Jiang Yang became a little nervous.

"Does it matter? Our opponents are not useless." Luosang said with his head up. In fact, he couldn't see anything. He seemed to be sniffing something in the thick fog. "Listen, lean carefully against the rocks marked on the map." On the edge of the beach, slow down to less than 4 kilometers."

"Slow down?"

"You don't know the way those planes search for tanks, they can spot things that are moving fast, but as long as we're slow enough, their radar is blind."

"Brother, how do you know?"

"The CIA's guerrilla warfare course taught me how to deal with fighter jets. I worked hard back then. It's a pity that I can't see it with my own eyes in this life. The day I fight back."

As he spoke, he became a little sad.

Standing on the open-air console on the upper floor, Jiang Yang carefully controlled the boat to move to one side, and it would approach the edge of the jagged rocks in the river. The boat bumped into the rocky beach from time to time, but the side of the boat was full of tires. , can withstand general impact.The captured Beidou satellite positioning system is accurate to the meter level and can provide control routes, but at low speeds, the rudder effect of the ship is not very obvious, making it difficult for laymen to control.

The roaring fighter jets flew overhead for the second time, this time from west to east. It can be seen that the Chinese army is really searching here carefully, like using a sieve to sift out tiny lice. Unfortunately, today they encountered a rather serious Foresighted opponents will inevitably be caught blind.Lausanne's preparations are very good. In addition to the anti-infrared modification of the ship, the mast and chimney are also removed, which makes it difficult for radar imaging to distinguish the shape of the ship.

The fighter pilots flew smoothly over Tespur, and did not find the 15 to 25-meter-long ships that the command wanted-this is the target characteristic estimated by Lin Huaisheng.The radar only saw the helicopter flying on the river, obviously it was his own, other than that, no suspicious ships could be found.

At this moment, Lin Huaisheng's headquarters has withdrawn to the back of a slope 9 kilometers away from the Brahmaputra River to avoid possible attacks.In the silence, Lin Huaisheng looked at his watch pretending to be calm. It was already 3:40 in the morning. According to his estimated speed of the enemy ship, it should have arrived by now. He had already prepared for the worst, but the sound However, nothing happened for a long time, and Lin also began to mutter, did Luosang actually go by water?Or did he deliberately reduce the speed?In this way, he can avoid the stationary object filtering mode of the fighter radar.If so, how to deal with it?

"With such a thick fog, even if they want to attack along the river, they can't sail." Ding Keguang said, he still didn't buy Lin's judgment.

"Satellite positioning must be used. Maybe we can interfere with the GPS signal and immobilize them. As long as the fog clears after dawn," Lin said.

"If they have a Beidou terminal, what do you do? It's destroying our own navigation." Ding raised his eyebrows.

"Turning off the satellite navigation is also a solution." Lin frowned and said. In fact, he had already considered it. If necessary, interfering with GPS and shutting down the Beidou satellite signal can destroy the enemy's navigation ability, but after thinking for a long time, he thought it would be so costly Zhou Zhang's matter, the superior will not agree.

"How is the evacuation of downtown Tespur going?"

"We have photographed the troops to do the work of persuasion, but Western journalists are unwilling to retreat. They think that we smashed the door in the middle of the night to punish them for reporting on India."

"I don't know what the hell is going on. What's going on in the prisoner-of-war camp?"

"It's too late, I can only transfer as much as possible."

"It seems that casualties are inevitable."

A large anti-submarine aircraft with 4 rounds slowly flew to Tespur.This is a navy anti-submarine aircraft, and it is also Lin Huaisheng's last technical means.Although the radar of this large aircraft can search for objects as small as a periscope, it does not have a search mode for the ground. In fact, other photoelectric sensors on the aircraft are not suitable for this mission. Of course, the superior sent this aircraft to It's not unreasonable. There is a very long magnetic anomaly detector on the tail of this plane, which seems to be able to play a role. It was thought up by someone in the headquarters. Xu Jingzhe thinks it can be tried.Of course, if the opponent can foresee this situation, it is a big deal to change to a wooden boat.

After the movement of the fighter jets in the air disappeared, he did not come back for a long time. Standing at the bow of the ship, Lausanne guessed that his luck had worked again. It seemed that the enemy really had nothing to do with him.

Under the cover of night and fog, the ship slammed and bumped all the way to the final goal, which was less than 2.5 kilometers away.

"You see, even if the enemy has advanced weapons, we can still use our wisdom to fight against them. Facts have proved that our ideals are possible."

"Brother, you are too powerful, you have completely guessed the enemy's way." Someone said.

"You can defeat your enemies only by doing more and earlier than they think."

As he spoke, the ship lightly bumped against the rocks on the shoal again, and made a bang.Under Jiang Yang's clumsy control, such a collision would happen every few minutes, and everyone was no stranger to it.The boat has reinforced the penetration and sides with steel plates and tires and is not so easy to damage.

"Brother, it's okay, this broken ship will definitely last to the end." Jiang Yang explained to himself.

"Actually, I chose this strong and crashworthy iron-hulled boat to prevent such things." Lausanne said proudly, "This is the strongest boat left by the Indians."

"Listen! Something seems to be approaching again?"

"Yes, right above the head." Everyone stood still for a while, waiting for the voice to grow louder, and then gradually decreased again.

"They seem to have sent something different this time? The speed is quite slow."

"Hehe, as long as this fog doesn't clear, no matter how many planes they send, it will be unnecessary." Luosang said to himself, and now he has long been a god-like existence in the minds of his subordinates, so they will believe anything they say.

The radar operator of the anti-submarine aircraft in the air found that it was completely impossible to find suspicious targets from the sharpened and amplified radar images. There were too many fragmented riverbed protrusions below.However, the magnetic anomaly detector on one side suddenly had a signal, which indicated that the plane flew over a metal object just now.

The pilot checked the area where the signal was found and confirmed that it was not his own helicopter that interfered with the passive detector there.Of course, the situation here is much more complicated than that of the vast sea, and it cannot be ruled out that there is a metal reaction in some man-made building on the sandbar in the middle of the river.He decided to circle again and note where the signal reappeared to confirm that it was moving.Unlike the mode that relies on Doppler radar to filter out stationary (low-speed) objects, the passive magnetic anomaly detector can record and compare the location of the abnormality found on the electronic map, so that even if the target speed is very low, it can still be detected in the second time. When passing, analyze whether its position changes to judge whether it is moving.Of course, searching for submarines at sea does not need to do so much. Once an abnormality is found, the enemy can be directly determined and the buoy sonar or torpedo can be launched.
