Abstract

Interest in passive radar systems is increasing because of its hidden operational capabilities, cost effectiveness and low maintenance requirements. The greatest advantage of these systems is that they can detect and follow targets using the illuminators in the environment without the need for a dedicated transmitter. In recent years, the increasing number of wireless transmitters have begun to be gathered at a single point, creating new opportunities for passive radar systems. In this study, target detection performance in passive radar systems by using multiple frequency FM radio broadcasts from a common transmitter point is investigated. Accordingly, a real-time applicable method proposed that combines the singular channels on a broad frequency band with software based radio technologies to improve target detection performance. It has been shown that the proposed method improves the target detection performance of FM signals without introducing additional load to the system and reduces the performance fluctuations and ghost targets that are generated in passive radar systems due to the modulation content.
