Interesting article good read for defence fans

China Aviation Industry radar field has made a major breakthrough recently, successfully developed the world's first air-cooled air-cooled phased array fire control radar, the recent test flight proved successful. The use of efficient air cooling technology, successfully resolved the radar equipped with PD fighter is not a worldwide problem in situ direct transfer of active phased array radar, the Chinese air force F -10A and -11B models can be directly upgraded facelift.

Compared with the conventional mechanical scanning radar, the advantage of airborne active phased array radar is that it can realize the superposition and synthesis of the radiated power in space, so as to improve the detection performance of the radar. From the current point of view, the recent anti stealth technology of active phased array is more realistic and reliable way, there is the realization of two-dimensional scanning electron, is at the two level, the horizontal direction can be realized with electronic scanning, scanning speed, accuracy, data update rate is high, especially for dealing with high maneuverability, high speed and large number of the target, combined with the performance of multi beam active phased array radar, can deal with multiple targets, to achieve a variety of functions, thus giving more fighter functions.

The key technology of active phased array radar is T\/R module technology, especially to lower the cost of T\/R module and to increase the number of T\/R modules under the condition of keeping the performance. F -20 because head diameter is larger, the antenna can accommodate larger aperture, can T\/R module layout more appropriate, can reach about 2000, then the peak of airborne active phased array radar is about 6KW, the average power of 2KW, these data are not inferior to F22 AN \/APG-77, but this will bring active phased array radar "sweating" problem, air-cooled two-dimensional active phased array fire control radar Chinese research is a good solution to this problem.

The radar is the average power is more important, it directly determines the spatial information tracking and control ability of airborne radar, and the average power of active phased array radar than the mechanical scanning radar is more than 2 times higher, according to the radar detection distance, power is increased by 2 times, the detection distance can be increased by about 20%.
