Deception Jamming for Squint SAR Based on Multiple Receivers

A deception jamming method for synthetic aperture radar (SAR) based on multiple receivers is proposed. This method deals with the parameters of hostile SAR as a whole for deception jamming. By measuring the range differences between different receivers, higher accuracy can be achieved than detecting each of the parameters directly. The squint angle, which is hard to be obtained for the electronic reconnaissance, is also included in the parameters the multireceiver system gets, so this method works on the squint SAR. The accuracy of the algorithm and the system noise are analyzed. Simulation results verify the effectiveness of the algorithm.
