Super Weapon Swap System

At present, many countries with backward technology still adopt the style of pot cover. This kind of antenna is the most backward. Huge energy is wasted, and there is no one in a hundred miles that is transformed into electromagnetic wave.

How can we radiate energy more effectively? At this time, a flat slot radar antenna appears. The antenna is a large flat plate. It radiates electromagnetic waves through those precision machined slots, which has higher work efficiency and reduces the weight of the antenna.

Even the chicken country has not mastered this technology. Only the eagle country has applied it maturely. At the same time, this is a technology just mastered by the Han country.

Yes, even Han has just mastered the processing of this radar antenna, which has leapt to the world advanced level. On this basis, a series of products can be developed, and large-scale applications are in sight.

However, this still belongs to mechanical scanning radar, that is, the antenna still needs to rotate, which is limited by the rotation speed of the antenna, its refresh rate and so on.

One of the most important indicators of the fourth generation aircraft in the future is phased array radar, which appears to eliminate the shortcomings of mechanical scanning radar.

The basic principle of phased array radar is that the radar antenna does not realize beam scanning through mechanical rotation, but electronically controls the phase of the unit constituting the antenna to realize spatial scanning of the antenna beam.

Due to the realization of electronic scanning, phased array radar can quickly scan a large airspace in a very short time, truly realize multi-target search, tracking and attack, and realize a variety of functions, such as ground / sea search while working in the air.

Various advantages make it have broad application prospects. Let alone simply take the Xiaolong fighter as an example. If we just replace the radar with phased array radar, the combat effectiveness of the whole fighter can be improved by at least 50%.

The concept of phased array radar came out in the 1950s. In the 1960s, eagle and bear have developed large-scale land phased array radar. However, these are passive phased array radars and are too large to be put on the carrier aircraft.

Passive and active, also known as passive and active, that is, whether it is a separate component or a single component that transmits radar signals.

Only when discrete parts are used to form transmitting / receiving units (i.e. T / R components), such radar is advanced.

In 1964, Yingguo people launched the microelectronics application radar program - Mera, developed the principle prototype of active phased array radar with 604 unit arrays for the first time, and achieved satisfactory test results.

The reliable airborne Solid-state Radar program rassr carried out by the eagle people in the 1970s is the second stage of the development of airborne active phased array fire control radar. An active array with 1048 T / R components is developed, which solves the thermal design problem in the array and provides a reliable working environment for the T / R group, so as to make the array work reliably.

These experiments were all successful.

On the basis of the completion of the first two stages, the eagle people started the SSPA (solid state phased array) program in 1983, developed an array with 2000 units, and used GaAs GaAs FET (field effect) devices in t / R modules for the first time to directly amplify X-band signals, greatly improving power efficiency.

The research work in these three stages has laid a foundation for the development of an / apg-77 radar equipped with F-22 aircraft.

Relying on the good relationship with the eagle country, it can be said that what the eagle country has, Davidson can have. Now, Davidson must have obtained the research results of the second stage.

On the basis of these technologies, Davidson has also carried out research and development. Their main purpose is not to be used on board, but to develop early warning aircraft.

Without early warning aircraft, there will be no way to see ultra-low altitude fighters, and there will be loopholes in the air defense system. Eagle's E-3 early warning aircraft has a large rotating plate on the body, which is equipped with a flat slot antenna to scan.

The Falcon early warning aircraft developed by David in later generations has removed the big plate and turned into a big nose and big cheeks on both sides.

Technology is not achieved overnight. The rapid progress of the Han state is due to the existence of Qin Guan, a fierce man. Now, glasuton was stunned when Qin Guan said he wanted these technologies. How is it possible? If these technologies were given to the Han state, the eagle state would never let them go.

After all, the self-developed fighter is just a plan. If not, we can buy world-class advanced fighters from Eagle country at any time, even if Eagle country refuses to export because of the domestic and foreign environment, and internal personnel smuggle them out.

Such technology exchange is not cost-effective.

"President Qin, we can't agree to your proposal. We can take your proposal back to China for discussion," glassA said.

Qin Guan smiled. Technology for technology. Do you want to fool us if you don't show sincerity? It's not that easy.

Of course, flicker has just begun. There are many more behind. I'm not afraid you won't take the bait.

"However, we can exchange other ones. Mr. Qin, do you have any other suggestions?" glassA continued.

"Oh, that's right." Qin Guan continued to meditate. The time was actually very short, but it was a kind of suffering for the people of the kingdom of David. Finally, Qin Guan spoke.

"Then let's use the hubby anti radiation UAV and adm-160 MALD air launched decoy bomb."

What Qin Guan said made the other party speechless again. These things are key high-precision weapons related to national defense and security. Any kind of weapons can't be exported.

GlassA's face was very ugly. Finally, he wriggled his throat and spoke again: "President Qin, do you think this is OK? How about we use money to buy it?"

Don't mention technology exchange. These technologies can't be exported to the Han country. Just use money. Davidians are the most profitable people in the world.

Qin Guan shook his head: "we are not short of money."

This sentence is quite shocking. Is there no shortage of money in the Han country? What a bull. Your foreign exchange reserves are not enough for us to make a change.

"Besides, how can we buy the country's important weapons with money?" Qin Guan continued: "it seems that let's put aside the j-9 project and continue to talk about our j-14. How many do you plan to buy? If you want to export the production line, we can start selling at least 50."

Of course, the shrewd David people can see that this is because they have repeatedly pushed three obstacles and four obstacles, which has annoyed president Qin. They don't want to change technology for technology? The j-14 project will also jam you. Hum, you took the initiative to find it.
