Optimal Sensor Selection for Jammer Identification

Deception jamming is a powerful technique used to disrupt various radar systems. In this work, we propose a novel sensor selection scheme for FDA-MIMO radar systems designed to maximize the likelihood of accurate jammer identification. The approach exploits the inherent delay between a jammer measuring incoming waveforms and its response. This delay induces a slight shift in the perceived distance across different receivers, known as the deception range, enabling differentiation between jammers and true targets. The proposed sensor selection scheme is formulated to minimize the achievable variance of the deception range, enhancing identification accuracy.
