无源雷达及其基于手机基站的定位方法研究

Passive Radar and Positioning Method Based on Mobile Phone Base Stations

随着电子对抗技术的日益升级，有源雷达因为容易被敌方定位而面临严重威胁，而基于调频广播和电视信号等民用外辐射源的无源雷达能大幅度提升雷达及平台的生存能力。本文对无源雷达的特点进行了介绍，阐述了基于手机基站的无源雷达探测方法，并提出了关键技术的解决方案。

With the escalating electronic countermeasure technologies, active radar is facing a serious threat from enemy because of being susceptible to detection. With the use of other civil radiation sources such as the FM radio and television signals, passive radar will greatly improve the survival of the radar and platform. In this paper, the characteristics of passive radar are introduced and a detection method of passive radar based on mobile phone base stations is detailed. A solution of the key technologies is presented.
