Chapter 694: We are not short of money

Now, in many countries with backward technology, the radar antenna used is still the style of the pot cover. This kind of antenna is the most backward, the huge energy is wasted, and there is no one in the world that turns into electromagnetic waves.
How can the energy be radiated more effectively? At this time, a flat-slot radar antenna appeared. The antenna is a large flat plate, which radiates electromagnetic waves through those precision-machined slits, which has higher working efficiency and can reduce the weight of the antenna.
This kind of technology is not even mastered by the chicken country. Only the Eagle country has matured its application. At the same time, this is also a technology that the Han country has just mastered.
That's right, even Han Guo has just mastered the processing of this kind of radar antenna, and thus has jumped to the world's advanced level. On this basis, a series of products can be developed, and large-scale applications are in sight.
However, this is still a mechanical scanning radar, that is to say, the antenna still needs to rotate, limited by the speed of the antenna rotation, its refresh rate, etc., the indicators are maintained at a very low level.
One of the most important indicators of the next four generations of aircraft is the phased array radar, which appeared 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 uses electronic means to control the phase of the elements that make up the antenna to achieve spatial scanning of the antenna beam.
Due to the realization of electronic scanning, the 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 working in the air At the same time, other tasks such as land/sea search are carried out.
The various advantages make it have a wide range of application prospects. Let alone a simple example of the Xiaolong fighter. If the other is not changed, just replace the radar with a phased array radar. Then the combat effectiveness of the entire fighter can be increased by at least percent. fifty.
The concept of phased array radar came out in the 1950s. In the 1960s, Eagle State and Xiong State had developed large-scale land phased array radars. However, these are passive phased array radars, and they are huge in size and cannot be placed on aircraft. Come up.
Passive and active are also called passive and active, that is to say, whether the radar signal is transmitted from a discrete component or one.
Only by using discrete parts to form a single transmitting/receiving unit, (that is, t/r component.) Such radar is advanced.
In 1964, Ying Guoren launched the Microelectronics Application Radar Project-MERA, and developed the first prototype of active phased array radar with 604 unit arrays, and achieved satisfactory test results.
The reliable airborne solid-state radar project carried out by the Eagles in the 1970s-RASSR is the second part of the development of airborne active phased array fire control radar. An active array with 1048 T/R components was developed, in the array It better solves the thermal design problem, provides a reliable working environment for the T/R group, and makes the array work reliable.
These experiments have achieved complete success.
On the basis of the completion of the first two phases of work, Yingguoren started the SSPA (Solid State Phased Array) project in 1983 and developed an array with 2000 elements. For the first time, GaAs GaAs FET (Field Effect) The device directly amplifies the X-band signal, which greatly improves the power efficiency.
The three stages of research work laid the foundation for the development of AN/APG-77 radar equipped with F-22 aircraft.
Relying on the good relationship with the Eagle Nation, it can be said that the David Nation can have whatever the Eagle Nation has. Now, the David Nation must have obtained the second phase of research results.
David State also conducts research and development on the basis of these technologies. Their main purpose is not to use them on airborne, but to develop early warning aircraft.
Without early warning aircraft, there would be no way to see fighters flying at ultra-low altitudes, and there would be loopholes in the air defense system. Eagle Country’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 Faircon early warning aircraft developed by the Kingdom of David in later generations has removed the big plate and turned into a big nose and big cheeks on both sides.
Technically, it was not accomplished overnight. The rapid progress of Han Guo is because of the existence of Qin Guan. Now, when Qin Guan said that he wanted these technologies, Graça was stunned. How could it be possible? If these technologies were given to Han, then Eagle would definitely not let them go.
After all, self-developed fighter planes are just a plan. If not, you can buy world-class advanced fighter planes from Eagle Nation at any time, even if it is because of the domestic and foreign environment that Eagle Nation refuses to export and internal personnel are smuggled out.
Such a technology exchange is not cost-effective.
"Mr Qin, we cannot agree to your proposal. We can bring your proposal back to China for discussion." Graça said.
Qin Guan smiled, technology for technology, do you want to fool us if you don't show sincerity? Where is it so easy.
Of course, the flicker has just begun, and there are many more later, so I am not afraid that you will not be hooked.
"However, we can exchange it with others, Qin, do you have any other suggestions?" Graça continued to ask.
"Oh, that's it." Qin Guan continued to look contemplative. This time was actually very short, but for the people of the Kingdom of David, it was a torment. Finally, Qin Guan spoke.
"Then Habi Anti-Radiation UAV and ADM-160MALD air-launched decoy."
What Qin Guan said made the other party speechless again. These things are key high-precision weapons related to national defense and security, and it is impossible to export any of them.
Graça's face was very ugly, and finally, his throat wriggling, he spoke again: "Mr Qin, do you think this is okay? How about we buy with money?"
Not to mention the technology exchange, these technologies are impossible to export to the Han country, so just use the money. David is not short of money, and the 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. Does Han State lack money? What are you bragging about? Your foreign exchange reserves are not enough for us.
"Furthermore, how can the country's heavy equipment be bought with money?" Qin Guan continued: "It seems that we put aside the J-9 project and continue to talk about our J-14. How many do you plan to buy? If we export the production line, we will sell at least 50 frames."
The shrewd people of David can of course see that this is because their repeated pushes have made Mr. Qin a little upset, don't want to change technology? On the J-14 project, you will also be stuck, huh, you found this on the initiative.
