Abstract

Although the ambiguity function of Beidou signal is roughly shaped like a pin, there still exists some sidelobes, which would inevitably reduce target detection performance of passive radar to a certain extent. However, this feature has been ignored in the existing literatures. In this paper, the signal characteristics of Beidou passive radar are analyzed, and a simultaneous range domain and Doppler domain window adding technique is proposed, which can reduce the sidelobes effectively and improve conventional target detection performance over 3 dB. Simulation results demonstrate the effectiveness of the proposed method.
