In this paper results of an experiment using a multistatic passive radar system based on packet wireless network illuminators are presented. The network consists of several transmitters/receivers that operate on the same channel and exchange data with each other. The passive radar listens to the communication and performs decoding of captured frames, and determines the WiFi network node which was the source of the transmitted frame. The received data stream is divided, based upon the decoded source address, into data streams sent by each network node, after which the separated data streams are processed using classical Passive Coherent Localization methods in order to detect target presence and to localize detected targets. The paper presents details of the experiments performed and their results.
