摘　　要：介绍一种脉冲压缩雷达的信号处理体系结构,特点是全系统的处理模块MTI、脉压、MTD、CFAR均采用浮点DSP来完成处理。这种实现方式较采用FPGA实现的优点是可省去大量的FPGA编译时间,不用考虑动态范围不足的问题,适合团队式并行编程、开发,软件易于维护,系统稳定性、可靠性得到明显提高。The structure of a signal processing system in the pulse compression radar is introduced.The floating-point DSP is adopted to implement the signal processing by the modules of MTI,plus compression,MTD and CFAR.The advantage of this approach compared with FPGA is that a large amount of developing time is economized and the dynamic range of the signal need not be considered.Therefore,it is suitable for the paralell programming and development by agroup at same time,and the software is easy to be maintained.The practical application shows that the system is stable and the reliability is improved apparently.
