After an introduction to bistatic/multistatic radar systems, the talk will focus on multistatic passive radars. The characteristics of the systems with different sources of opportunity will be described. The concept of bistatic ambiguity function (BAF), often used to measure the possible global resolution and large error properties of the target parameters estimates, will be introduced and its relation with the Fisher Information Matrix (FIM) and Cramér-Rao Lower Bounds (CRLBs) highlighted. Some example will be provided concerning active LFM radar and passive radar using an UMTS or FM signal as source of opportunity. The information gained through the calculation of the bistatic CRLBs can be used in a multistatic radar system for the dynamic choice of the optimum Tx-Rx pair or set of bistatic channels for radar target tracking in a multistatic scenario. Taking advantage of the knowledge of the CRLBs is a kind of “radar cognition”, that, applied in multistatic realistic scenarios with both active and passive sensors, can improve the performance of the target tracker and reduce the computational load of surveillance operations. Some results will be shown in both certain anduncertain radar measurements.
