摘　　要：就无源双(多)基地雷达问题,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信号的特点,分析了以其作为照射源的雷达系统的可行性,并给出了定位方法,以及降低直达波及周围基站干扰的方法。Discusses the use of GSM signal as the opportunity illuminator for a bistatic （multistatic） radar system. The passive radar system uses the downlink signals from the GSM base station as the transmissions of opportunity. The character of GSM signal is analyzed and the feasibility of this radar system is given in detail. The methods of location and reducing the interference of direct path signal and around the base station are given.

关 键 词：机会照射源 GSM 无源定位
