Abstract

An adaptive array radar employing the Joint Domain Localized-Generalized Likelihood Ratio (JDL-GLR) test is compared to a displaced phase center aperture (DPCA) radar. The JDL-GLR test is a two-dimensional transform domain localized adaptive algorithm which decouples the total degrees of freedom from the measurement data sample size. The results presented are for targets in a highly nonhomogeneous clutter and jammer environment where conventional adaptive array processing is not feasible.
