Design Of Terminal Guidance Radar Signal Processor System

In modern battlefield, the electromagnetism environment is more and more bad. The terminal guidance radar of a ASM missile has to detect and trace targets in strong background clutter.,and has to antagonize sundry jamming, such as active RF jamming, RGPO/RGPI jamming, etc.A new terminal guidance radar processer is introduced in the dissertation. The basic theories of the system and methods of signal processing such as orthogonal transform,digital pulse compression, velocity compensate, anti-chaff jamming, mono pulse angle tracking, etc. are expatiated at first; Next, the paper gives the design and realization of the radar signal processing system base on ADSP TS-201S and FPGA, including the hardware circuit design and software programming. At last, a method based on Kalman filter and HOJ to antagonize active RF jamming, RGPO/RGPI jamming is introduced.The analysis result of outfield experimentation data shows that this terminal guidance radar can detect and trace the target well.
