摘要
本文根据综合脉冲 /孔径雷达采用多个天线同时向全空域辐射多个载频信号 ,而在接收端通过信号处理获得发射方向图的特点 ,提出一种新的雷达体制———舰载无源综合脉冲 /孔径雷达 .该雷达既利用在岸上发射、在舰船上接收而构成岸 舰双 /多基地“广播式”雷达 ,又由于在接收站不发射信号而相当于无源定位 .本文介绍该雷达的基本组成、工作原理及其特点 ;分析其性能 ;讨论该雷达需解决的关键问题 .
A new type of radar system of ship based passive Synthetic Impulse and Aperture Radar(SIAR)is presented on the basis of multiple frequency carrying signals transmitted with multiple antennas to the whole directions,while its transmitting beams are formed by digital signal processing in receivers.The system shall not only make up a radar system of bi station or multi station through transmitting signals from the bank,and receiving signals on ships,but also be equivalent to a passive position locater at the sink.The basic constitutions and operational principles are presented.There are many distinguished features in the new radar system in comparison with conventional radars.Its performance is analyzed and simulative results are given.Finally,some key problems to be solved are discussed in the radar.
