摘要
雷达动目标检测的实时信号处理原来一般用模拟器件和通用数字信号处理器（ＤＳＰ）实现；本文设计了基于数字专用集成电路的雷达动目标检测实时信号处理系统。本文对该信号处理系统的雷达背景视频产生、单元平均恒虚警率（ＣＦＡＲ）检测、杂波图形成、动目标提取、视频信号积累、雷达定时器和控制器等用现场可编程门阵列（ＦＰＧＡ）进行了专用集成电路设计。该系统性能稳定、抗干扰能力强、体积小、便于调试，已投入实用。
Instead of analog device and general purposed DSP previously used in real-time MTD radarsignal processing , an ASIG-based radar signal processing system is proposed. In this system, the radar back-ground generator,the clutter-map unit former, the moving target signal extractor, the video signal integrator, theCFAR ( Constant False Alarm Rate)operator, the timer and controller are all designed by ourselves with FPGA.This system is now thrown into application with high performance, well-resistance to EMI, less circuit area, easeto debug .
