摘　　要：随着测试参数种类增加,测试环境越来越复杂,海量雷达数据与有限存储容量之间的矛盾日益明显,实时数据采集与压缩技术可以缓解这一矛盾的加剧。雷达数据采集系统采取了基于FPGA的LZW实时无损压缩算法。该算法能够实现追求采集信号精度的同时减低算法难度,已成功应用于某飞行测试实验,性能指标满足应用要求。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.
