  Abstract

FM radio-based passive radar is a radar system that estimates the position and speed of a target using an FM radio signal, which is one of the various broadcast signals. This FM radio-based passive radar uses a reference signal and a target echo signal to derive CAF (cross-ambiguity function). Using the derived CAF, the time difference of arrival and the frequency difference of arrival are estimated, and finally the position and velocity of the target are calculated. However, due to the structure of the received FM radio signal, sidelobes may occur on the CAF’s FDOA (frequency difference of arrival) domain, which may result in false detection that degrades the detection performance of the passive radar. In this paper, after analyzing the occurrence pattern of the sidelobes formed at the FDOA domain, we propose a method to remove the false detection results caused by sidelobes and show the effective performance of the proposed method.
