Abstract: Passive radar is of interest in many aspects. These radars accomplish target localization by receiver sensors. In this paper, we investigate the effect of the sensors arrangement on the performance of multi-transmitter and multi-receiver passive radar and present a method to maximize target localization accuracy on the important locations by the optimal arrangement of receiver sensors. The proposed method is based on the Cramer-Rao lower band. The optimal placement of receiver sensors can be achieved with the help of the proposed method. We investigate the types of sensors arrangement for better accuracy in the surveillance area. The provided Cramer-Rao lower band is developed for the use of time difference of arrival measurements and the angle of arrival measurements. As illustrated in the simulations results, the joint use of both the time difference of arrival and the angle of arrival is better than the use of them alone. Furthermore, the blind areas caused by the receiver sensors arrangement are eliminated by the joint use of measurement. On the other hand, the target localization efficiency increases with the increasing distance between sensors and their dispersion in the environment.
