Multi-Dimensional Interference Rejection & Target Detection in Early Warning Airborne Radar

Abstract

A study of the effects of mutual coupling and non-homogeneous data on the performance of adaptive algorithms (both covariance matrix based and least squared error) for Space Time Adaptive Processing (STAP). This effort addresses some of the issues in applying adaptive processing to real world, measured, data, by looking at the performance of two approaches: the JDL and D3 algorithms. Section 1.0 is an Introduction to the material in this report. Section 2.0 is a detailed analysis of the issue of mutual coupling and near field scattering. The section presents examples to illustrate the impact of mutual coupling on both D3 and statistical algorithms. Section 3.0 discusses the issues of non-homogeneous data, the use of a non-homogeneity detection and direct domain processing in non-homogeneous conditions.
