摘要
导航雷达在目标探测、海上避碰等方面发挥着重要的作用,是现代船舶不可或缺的设备。导航雷达数字信号处理机利用数字信号处理器处理雷达电磁波的回波信号,进行各个频段回波信号的过滤、处理,最终获取被测目标的详细信息。船舶导航雷达系统的目标探测精度与信号处理机的性能有密切的关系,因此,有必要针对雷达数字信号处理机进行优化升级。本文研究雷达数字信号处理机的FPGA电路设计和优化,从信号采集、存储和处理电路等方面进行了阐述。
Ship navigation radar plays an important role in target detection and ship collision avoidance.It is an indispensable equipment for modern ships.The function of navigation radar digital signal processor is to use the digital signal processor to process the echo signal of radar electromagnetic wave,filter and process the echo signal of each frequency band,and finally obtain the detailed information of the measured target.The target detection accuracy of ship navigation radar system is closely related to the performance of signal processor.Therefore,it is necessary to optimize and upgrade the radar digital signal processor.This paper focuses on the FPGA circuit design and optimization of radar digital signal processor,and details the signal acquisition,storage and processing circuits.
