Ways to improve the operating characteristics of radar systems

Abstract

Radar systems to air-cover critical and military infrastructure are used widely in the world armies. The main systems are mobile radar stations (radars). For most radars, the maximum target detection range with an effective scattering area of 3…5 m2 (for example fighter) does not exceed 200…250 km, taking into account the target speed of 0.8…1.8 Mach. Sometimes, it does not provide enough time to be hit by air defenses. The radar range is affected by several factors. First, it is the power of the electromagnetic wave transmitter. Assuming that all factors (other than transmitter power) are constant, then it is possible to determine from the radar equation [1] that to increase the radar distance by 20% it is necessary to double the transmitter power. Now this is virtually impossible for mobile radars due to the lack of high-power transmitters that are small in size and consume little electricity.
