基于综合脉冲与孔径技术的多基地“无源”定位系统

Multistatic "Passive" Location System Based on Synthetic Impulse and Aperture Radar (SIAR) Techniques

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 ,提出一种新的多基地“无源”定位雷达系统。该系统既利用在岸上发射、在舰船上接收而构成岸 -舰多基地雷达 ,又由于在接收站不发射信号而相当于无源定位系统。本文介绍该系统的基本组成、工作原理及其与常规地波超视距雷达、双 /多基地雷达相比的显著特点 ;给出计算机模拟结果 ;

This paper proposes a new multistatic 'passive' location radar system which, based on the SIAR techniques, uses multiple antennas to emit simultaneously multiple carrier signals to the space and obtains the transmission pattern through signal processing in the receiver stations. As it transmits in the coastal area and receives on ships, it constitutes a coast ship multistatic radar, and as its receivers make no transmission, it acts as a passive location system. This article describes its basic composition, working principle and characteristics as compared to conventional ground wave over the horizon radar and bistatic/multistatic radar, and gives out the computer simulation, finally discusses some key problems of this radar which need be solved.
