基于机会发射无源雷达系统采用的是一种古老而特殊的雷达体制，由于其具有潜在的隐蔽和反隐身等特性，近年来倍受媒体关注。专家们认为它将成为今后10-20年内雷达系统的一个重要发展方向。本文分三个阶段对这一系统的发展作了阐述，并评述了各个阶段的技术特征，最后对开展基于民用机会发射无源雷达系统关键技术的研究提出了几点建议。

The passive radar system based on transmitters of opportunity is an old and special radar system. In recent years it is the potential particularity, such as covert and anti stealth, that the media has shown considerable interest in its status. Experts think that it will become a crucial trend of radar systems in the coming ten or twenty years. In this paper, three stages in the history of transmitters of opportunity based passive radar system is reviewed. At each stage some of technical characteristics are analyzed. In the end, some suggestions and related problems on investigation of passive radar system based on civil transmitters of opportunity are also discussed.
