基于 OFDM 的被动雷达目标检测方法∗
A Target Detection Method of Passive Radar Based on OFDM
摘要
Abstract
The OFDM communication has been applicated widely.Base stations are widely spread in ur-ban.In order to detect the low-altitude targets,the method that combines the OFDM signal generated by base stations with the passive radar antennas array can receive the echoes of low-altitude targets.After signal processing,low-altitude detection and early-warning can be realized.At first,the uniform circular array model is established and the echo model of OFDM signal is deduced.Then,the method that gets the infor-mation of azimuth and pitch based on digital beam forming and an improved constant false alarm rate detector is presented.The integration effect is obtained according to the result of the 3D target detection.At last,the availability of the proposed method is proved through simulation and analysis.关键词
