Bibliography:Recently, the test parameters are increasing fast and the environment of test is more and more complex. With the development of the contradiction between mass data of radar signal and data storage, the real-time data compression algorithm can solve the above problem. Real-time lossless compression algorithm LZW based on FPGA is applied in the radar data acquisition system. This algorithm can ensure the sample precision of radar system and simplify algorithm difficulty and, which has been applied in flight test experiment. The performance indexes meet the requirement.
