Abstract

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.
