基于外辐射源的无源定位系统是以电视或调频广播的发射机作为其辐射源的，具有反侦察、抗干扰、反隐身、抗反辐射导弹的潜在优势，有良好的发展前景。文中首先通过对基于外辐射源的无源定位系统的原理分析，指出基于外辐射源的单站无源定位系统实际相当收发分置的双基地雷达，并得出其作用距离程，然后对理想条件下的干扰有效区进行了分析，得出压制区边界方程，最后对计算机仿真计算结果进行分析总结。

Passive location aided with opportunity transmitter is a kind of system which employs a television or FM broadcast transmitter as the illuminator. Some advantages are obtained from this radar, such as anti-elint, electronic counter-countermeasure, detection of stealth targets and counter anti-radiation missile. First, the theory of the passive location system based on opportunity transmitter is analyzed, thesingle station passive location system based on opportelity transmitter is pointed out, and process distance equation is elicited. The jamming area efficiently under ideal condition is analyzed and pressing area borderline equation is elicited. Finally, and the result of the computer simulation is also analyzed and summarized.
