Research On Radar Reconnaissance Receiver And Signal Processing Board Design

Along with the development of A/D device, the multiformity of radar system and the improvement of DSP speed, the research of key technology of radar reconnaissance receivers concentrate on minimum features'analysis of pulse signals.It is necessary for radar reconnaissance receivers to have the alility to analyze and process all kinds of radar signals quickly and conrrectly in order to meet the requirement of the war in the future.The radar reconnaissance'mission, operational principle,technoloy requirements and the methods of the minimum feartures analysis are introduced, then The study of the linear frequency modulation signal (LFM) base on Short-Time Fourier Transform and Wigner Distribution are discussed in detail. Their characters, advantages and disadvantages are given with computer simulation.Acorrding to the algorithms, a hardware platform is set up using TS201 mainly. The design of power, clock, strorage, DSP and FPGA and so on are detailedly described. Then tested the platform and indicated something should be pay more attendtion. Finally,WVD arithmetic is fleetly realized by DSP.
