Signal dependent clutter waveform design for radar STAP

Abstract

Waveform design is a pivotal component of the fully adaptive radar construct. In this paper we consider waveform design for radar space time adaptive processing (STAP), accounting for the waveform dependence of the clutter correlation matrix. Due to this dependence, the joint problem of receiver weight vector optimization and radar waveform design becomes an intractable optimization problem. Therefore, we consider constrained versions of the alternating minimization algorithm, which, at each step, optimizes the STAP weight vector and waveform independently. Our simulations reveal a non-increasing error variance at the output of the filter.
