一种雷达信号处理机的软件设计

摘要

结合某雷达信号处理机研制项目,对该雷达信号处理机的脉冲压缩、动目标显示和动目标检测、恒虚警处理等软件进行设计。论文首先回顾了该处理机用到的几种雷达信号处理方法：线性调频信号的脉冲压缩、基于一次相消器和二次相消器的动目标显示、通过窄带多普勒滤波器组的动目标检测处理、恒虚警检测等方面的工作原理和实现方式。根据信号处理机硬件平台设计了相关的信号处理软件,并实现上述信号处理功能。%Based on the development project of a radar signal processor,the software of the signal processor such as the pulse compression,MTI,MTD and CFAR is designed.The working principles and implementation of some radar signal processing methods such as the pulse compression of LFM signals,the MTI based on the primary and secondary cancellers,the MTD processing based on the narrowband Doppler filter banks,and the CFAR detection are discussed.The relevant signal processing software is designed with the above functions implemented according to the hardware platform of the signal processor.
