摘　　要：目前利用机会照射源的被动式双(多)基地雷达得到广泛关注,可用的外辐射源有电视广播信号、卫星信号等,论述了一种新的机会照射源——GSM信号。利用GSM基站的下行信号为发射源构成被动式雷达系统,详细地分析了GSM信号的构成形式及特点,分析了以其作为信号源的雷达系统的可行性。同时仿真了该雷达系统的探测覆盖范围,并给出了目标检测及定位方法。Passive bistatic （multistatic） radars using illuminators of opportunity have attracted much attention recently. Some illuminators can be used, such as TV transmissions, broadcast systems, and satellite signal. This paper discusses a new illuminator, that is, GSM signal. The passive radar stem uses the downlink signals from the GSM base station as the transmissions of opportunity. The waveform and character of GSM signal are analyzed and the feasibility of this radar system is given in detail. The simulation of the detective range and the method are shown in the paper.
