A procedure for effective receiver positioning in multistatic passive radar

Multistatic passive radar systems offer many advantages in terms of coverage and sensitivity of the positioning accuracy with respect to the single bistatic passive radar. However the performance of such a system is largely dependent on the geometry. Its design has to deal with the additional complexity of selecting both the optimum transmitters among the ones available and the optimum receiver position. In this paper we identify the set of constraints for the relative positions of transmitters and receivers, in order to guarantee the continuous monitoring of an assigned target path. Then, we focus on the specific case of a multistatic passive radar based on two transmitters of opportunity and a single receiver. For this case, we devise an optimised approach to select the two transmitters among the available transmitters choose the receiver location.
