摘要/Abstract

摘要： 无源雷达系统实际探测能力与实际应用场景中多种因素密切关联。提出了一种基于实测信号与探测目标动态特性相结合的仿真评估方法,利用实际无源雷达接收系统获取参考通道和监视通道的环境信号,利用参考通道重构直达波,结合针对目标的运动特性和散射特性,在直达波上调制回波功率、时延、多普勒信息,得到目标回波并叠加在监视通道中得到监视信息,对参考通道和监视通道进行常规的信号处理,通过蒙特卡洛仿真获得针对目标的发现概率,可用于评估实际场景中针对特定目标的无源雷达探测能力。

Abstract: Detection ability of the passive radar is very closely related with many factors in the real aplication. A method was proposed based on the raw data and the dynamic characteristics of a specific target. In this method, the reference and the surveillance channels' signals were obtained through the actual passive radar receiving system. The direct-path signal was reconstructed by using the reference signal. The target echo was obtained by modulating the direct-path signal with the echo power, delay and Doppler parameters, which was calculated with the move and scattering characteristics of target. Adding the target echo to surveillance channel, the final monitoring information was obtained. The conventional signal processing was applied on the reference channel and surveillance channel, and the detection probability of specific target was obtained through Monte Carlo simulation. This method can be used to evaluate detection ability of passive radar in the actual scene for specific target.

Key words: passive radar, simulation evaluation, raw signal, scattering characteristics
