Multistatic Passive Coherent Location radar systems

The use of signals of opportunity such as television or radio signals to detect and track targets has cyclically entered and left technology fashion. However, due to high constraints in the receiver design, and the signal processing implementation in real time, operational systems have appeared only recently. This paper present a multistatic passive coherent location (PCL) system, where the signal, issued from several transmitters, is processed coherently by several receivers organized in a network configuration. An analysis of the signal processing operations is presented and an efficient hardware implementation is described.
