Abstract :
This paper focuses on the accuracy analysis of the combined active and WiFi-based passive radar network. The Cramér-Rao Lower Bound is used as an accuracy metric. It is shown that localization performance of the active radar network can be improved with exploitation of the signals from passive bistatic WiFi radars. This makes reasonable to use information from passive and active radars simultaneously in order to enhance system localization capability. Sparsity-based algorithm is applied to find optimum geometry of the WiFi receivers at the fixed positions of the WiFi access points and active radars.
