摘　　要：介绍了用于脉冲多普勒 ( PD)雷达仿真系统的信号处理机的设计 ,该处理机在硬件设计中采用了 TMS32 0 C30高速数字信号处理器 ( DSP)和 PC机相结合的体系结构 ,采用零中频正交双路数字处理 ,结合高效的移位 FFT算法 ,使整个系统具有较高的灵活性和可扩展性。A radar signal processor for a simulative system of Pulse Dopler radar is developed. Based on the system architecture of combining of high speed Digital Signal Processors (DSP)--TMS320C30 with host PC, the processing device is real time and easy to expand. A zero IF quadrature two channel digital processing scheme is used. FFT algorithms include radix 4 algorithms and Shift Fast Fourier Transforms (SFFT) algorithms, which can improve accuracy of common FFT algorithms. Test experiments have proved that the radar signal processor can meet system demands.
