Paper Abstract

Cognitive space-time adaptive (STAP) radar system optimizes the receiving filter according to the time-varying clutter environment. Aiming at the optimization design of receiving filter, an optimization model of STAP radar filter is established, and a method of filter optimization based on Lagrange dual algorithm is proposed. Compared with the traditional adaptive STAP filter, the simulation results show that the performance of cognitive reception STAP filter is analyzed and verified. Compared with the traditional adaptive STAP filter, cognitive STAP filter can significantly suppress clutter and effectively improve the signal-to-noise ratio.
