Guidance Radar and Target Stackelberg Game in the Presence of Clutter

Abstract

Aiming at the problem of guidance radar waveform optimization for extended target detection in electronic warfare environment, the waveform optimization schemes of three different game strategy models are proposed. In the first two models, the waveform under clutter conditions is optimized through water-filling method based on maximizing signal-to-interference-plus-noise ratio (SINR) criterion. For the last case, an equilibrium solution between smart guidance radar and smart target under clutter conditions is given by theoretical derivation. With the criterion of maximizing SINR, the optimization waveform is obtained based on the max-min theory using two-step water-filling method. The simulation results demonstrate the effectiveness of the waveform optimization strategy for improving the performance of guidance radar for target detection.
