Abstract
A method for tracking an object of interest with a passive radar system using multiple radar sensors. The method includes the steps of receiving, with at least one controller, radar sensor characteristics and radar sensor locations data for a plurality of radar receivers occupying an area of interest. Data indicative of direct or reflected radar return signals from emitters of opportunity received by the plurality of radar receivers is also received at the controller. From this data, objects of interest are identified. The controller is configured to calculate optimized radar sensor parameters for the plurality of radar receivers for each identified object of interest, and transmit the same to the plurality of radar receivers for implementation. Radar return data received by the plurality of radar receivers using the optimized sensor parameters is provided to the central controller, and updated optimized sensor parameters according to the updated received radar return data are calculated.
