Netted radar and the ambiguity function

Abstract

In this paper, the key performance parameters of multistatic radar are investigated, via the netted version of the ambiguity function. A new tool has been developed for assessing the resolution and ambiguity properties for topologies assuming a radar network consisting of N transmitters and one common receiver, operating in a fully coherent or partially coherent mode. Combinations of monostatic and bistatic geometries are also considered. Simulation results outline the dependence of the multistatic ambiguity function on the relative positions of the nodes in the network and on the position of the target, but more importantly it shows the potential for enhancements in resolution and resolving ambiguities. Finally, the more complex case of N receivers and M transmitters is also developed, presenting two possible approaches for determining the overall ambiguity diagram of such a system.
