The struggle between modern electronic warfare radar jamming and anti-jamming is very fierce. The jammer produces multisystem and multi-type jamming signals, and the radar constantly improves its anti-jamming performance. Aiming at the comprehensive demand of radar jamming system for anti-interference performance test and evaluation of radar equipment, a radar reconnaissance and jamming system is designed and developed on the VST platform by using upper computer and FPGA technology, which can realize the comprehensive functions such as radar signal reconnaissance, multi-system jamming signal generation and radar standard calibration. The hardware scheme, reconnaissance and interference technology, FPGA function design and key FPGA module implementation are presented. The test results show that the system has high rf technical index, rich interference pattern, wide frequency band coverage, dexterity and versatility, and has certain application and promotion value.
