In this article, we have proved that using several passive radar receivers is of high interest to improve tracking capacities, by increasing the number of bistatic geometries available and diversifying the target aspect angles (multistatism). The experimental results showed that the multireceiver configuration enables us to initialize a track when the number of simultaneous detections is too low to do it in a single-receiver configuration (DVB-T) and/or it improves tracking quality, like track continuity, accuracy, and reduction of the initialization time (FM).
