摘要
无源雷达由于不发射电磁波,因而不易被敌方侦察系统探测到。特别是利用商业电台或电视台信号来照射、探测和跟踪目标的无源双/多基地雷达系统,既可不受反辐射导弹的威胁,又有潜在的反隐身探测能力,激起了人们的极大兴趣。而“沉默哨兵”代表了此类无源雷达的最新水平。本文将对“沉默哨兵”无源探测与跟踪雷达系统的研制情况、系统组成、核心技术等作一概述,旨在使读者对该系统有一个全面的了解。
Transmitting no electromagnetic wave, passive radar cannot be detected by hostile reconnaissance system. Especially, the passive bistatic/multistatic radar which uses commercial television and radio broadcast signals to illuminate,detect and track targets,cannot be threatened by anti-radiation missiles and provides the potential detection capability of the stealth targets. Great attention has been given to such passive systems. Silent Sentry represents the latest level of this kind of passive radar. In this paper,the development,composition and key techniques of Silent Sentry will be described as well as other relative researches.
