主要研究VTS（船舶交通管理）系统中的雷达信号处理系统。该系统采用基于DSP＋CPLD机制的实时信号处理板，两片C6X系列的高性能DSP和一大片大规模逻辑器件，实现对原始的雷达视频信号的各种处理：电子地图屏蔽、双极点滤波、匹配滤波、STC（Sensitivity Time Control)、恒虚警以及雨杂波处理。充分发挥DSP处理的优越性，在各种噪声和杂波中快速而准确地提取出船舶的各种信息，实现港口船舶的实时探测、定位和显示，并生成各种信息的统计报告。该处理器实际使用效果良好。

This paper is centered on radar signal processor for VTS( Vessel Traffic Service )system. The system is based on a real-time signal processing board whose mechanism is DSP + CPLD. Some methods including map masking, two pole filtering, matched filtering, STC (Sensitivity Time Control), CFAR, and rain clutter processing are applied to process original radar video signal by using two C6X DSP chips and one CPLD chip. With the advantages of DSP, this system can extract all kind of information about target vessels from noises and cluttes, detect,locate and display them and at the same time generate reports on these information. This processor has been put into use and the effect is desirable.
