Xu Sanduo's extra four brothers

"Minister, can you comment on many comrades' explanations on Portura?"

After a while of silence, Vice Minister Zhao Hanhai said to Shi Zhonghui beside him with a smile.

Minister Shi Zhonghuishi did not refuse, he looked at many Yu with admiration in his eyes.

"Hmm...Comrade Xu has a deep understanding of Portura! Its 'professionalism' is really impressive."

Immediately, Shi Zhonghui changed the subject and said: "However, there is a small problem, I still have to criticize you."

After hearing this, the bosses at the scene all showed surprise expressions.

Obviously, everyone didn't feel that there was nothing wrong with Yu's explanation just now.

In other words, everyone agrees with many redundant viewpoints!

Fortunately, Minister Shi quickly gave the answer.

He looked at Duo Yu with a smile, and said slowly, "I mean, don't try to talk nicely about Comrade Many Yu."

"Perfect people and perfect equipment almost don't exist, even the smallest flaws and faults will be magnified under certain conditions!"

"With the birth of any new equipment, both advantages and disadvantages coexist. You can't just talk about the advantages, but you have to mention its shortcomings."

"Only in this way, after realizing the advantages and disadvantages, can we make timely improvements and new models in the future."

After Minister Shi finished speaking, everyone couldn't help showing knowing smiles.

Needless to say, this boss is deliberately mentioning a lot of things.

Any genius has arrogance, but arrogance is like a double-edged sword, which can hurt both the enemy and oneself!
For this, a lot of reminders and reminders can also save people from taking some detours.

But after thinking about it carefully, everyone felt that Minister Shi's words made sense.

After all, for any new weapons and equipment, this advantage is easy to grasp.

But if its flaws can't be discovered in time and exposed in actual combat, the loss will be huge.

Therefore, after new weapons and equipment are designed, it is extremely important to pass the evaluation.

In the director's room of the war department, everyone laughed in good faith after listening to Minister Shi's teasing.

But the technical section chief and technicians on the side couldn't quite laugh.

Because they know that Minister Shi's words may not be completely ridiculed.

In fact, although the development momentum of radar early warning in the Republic is very good, there is still a big gap compared with the world's advanced level.

Especially now that the mysterious stealth bomber researched and produced by Stars and Stripes has gradually revealed some clues.

That mysterious stealth bomber put a lot of pressure on our military's coastline radar warning system.

Although this wave map radar system is the latest research and development achievement of our army, it is really a question whether it can detect the latest stealth bomber of Stars and Stripes.

At this time, Minister Shi asked many Yu to talk about the shortcomings of the portu radar, perhaps because of this concern.

Of course, many of the technical section chiefs and technicians in the Tianjin Navy District don't know what's going on in their minds.

So after Minister Shi Zhonghui asked, he quickly organized the language in his brain and started his own answer.

"It is indeed as the chief said, there is no perfect person, and there is no perfect weapon and equipment. If there are advantages, there will naturally be disadvantages!"

"The Botu warning radar is currently the best in our army's long-range warning radars. There is no doubt about this."

"Moreover, from an international perspective, this wave map warning radar can also be called the top level of the fourth-generation air defense radar. The word "excellent" is well-deserved..."

Having said that, Duo Yu paused for a moment, as if he was considering his words.

"However, this excellence is actually relative."

"Looking at the international advanced level, it has now entered the fifth-generation radar early warning system."

"The fourth generation and the fifth generation, put the two together, it is obvious that I am not only dwarfed, but also behind..."

After many Yu finished speaking, there was a burst of silence in the director's room of the Operations Department.

Shi Zhonghui, who was sitting in the first row, couldn't help but said: "Comrade Xu, most of you here are not radar professionals.

Taking this opportunity, by the way, I would like to share with you what the first-generation to fifth-generation radars are all about. "

Minister Shi gave orders, and of course many Yu had to follow suit.

"Radar is a transliteration of English Radar, derived from the abbreviation of radio detection and ranging, meaning "radio detection and ranging".

That is, using radio methods to find targets and determine their spatial positions.

Therefore, radar is also called "radiolocation".

Radar is an electronic device that uses electromagnetic waves to detect targets. It emits electromagnetic waves to irradiate the target and receives its echoes, thereby obtaining information such as the distance from the target to the electromagnetic wave emission point, the distance change rate (radial velocity), azimuth, and height. "

"The first-generation radar has low reliability and anti-jamming capabilities, and a high error rate. Its equipment time spans from the birth of air defense intelligence radar to World War I in the last century.

Since John Ying and Cross Germany were at war during World War I, John Ying urgently needed a radar (technology) that could detect metal objects in the air to help search for Cross Germany aircraft in anti-air attack warfare.

During World War II, radar technology for ground-to-air, air-to-ground (search) bombing, air-to-air (intercept) fire control, and friend-or-foe identification functions appeared.

The anti-jamming ability of the second-generation radar is significantly enhanced, but the reliability is still low, and the equipment time is after World War II.

Radar has developed a combination system of monopulse angle tracking, pulse Doppler signal processing, synthetic aperture and pulse compression with high resolution and identification friend or foe.

Combining computer automatic fire control system, terrain avoidance and terrain following, passive or active phased array, frequency agility, multi-target detection and tracking and other new radar systems.

"The third-generation radar is mainly based on the all-solid-state three-coordinate radar, which realizes fully automatic admission, fully automatic networking, and few people on duty and no one on duty.

The radar's electronic warfare environment adaptability and target environment adaptability have reached a relatively high level.Moreover, they all have certain anti-stealth aircraft and anti-radiation missile capabilities. "

Having said that, Duo Yu paused for a moment, smiled and said, "Now, we will add our port radar."

When everyone heard this, the expressions on their faces were relaxed.

Shi Zhonghui extended his hand to Duo Yu with great interest and said, "Go on, what's the situation with this fourth-generation radar?"

"The fourth-generation radar can be called air defense intelligence radar.

It can integrate the functions of surveillance, interception, tracking, identification and fire control support, as well as the collection of kill assessment information.

Its detection range, accuracy, electronic warfare capability, target recognition and adaptive capability, and reliability have all been qualitatively improved. "

"This type of radar began to be equipped and used in developed countries at the beginning of this century.

Representative models include the national missile defense system of Polar Bear and Stars and Stripes, and the multifunctional active phased array radar used. "

"As for the fifth-generation radar, our domestic fifth-generation air defense intelligence radar is still under development..."

"The principle of the fifth-generation radar of Stars and Stripes, with the scientific progress in various fields such as microelectronics, and the continuous development of radar technology, its connotation and research content are constantly expanding.

The radar detection method has been developed from the previous only radar detector to the fusion and cooperation of infrared light, ultraviolet light, laser and other optical detection methods.

The simultaneous multi-function capability of the fifth-generation radar enables battlefield commanders to scan targets in various search/tracking modes and automatically correct interference errors, and most of the control functions are completed within the system .

Automatic target recognition can maximize the role of weapon systems. Comprehensive radar systems with battlefield identification capabilities such as airborne early warning aircraft and JSTARS have actually become the information command center on the future battlefield. "

A lot of Yu's words are tactful, but the bosses can naturally hear it.

Needless to say, in terms of the technology of the fourth-generation radar, China still lags behind the developed countries of Western Stars and Stripes.
