Abstract

The nonhomogeneous clutter effect on covariance matrix estimation and on space time adaptive processing (STAP) performance is shown through the experimental multi-channel radar data analysis under the Multi-Channel Airborne Radar Measurements (MCARM) program. The importance of sample selection on adaptive weight formulation is demonstrated by the improvement in detection performance resulting from nonhomogeneity detector (NHD) prior to STAP. Two techniques for NHD are discussed: the SMI and generalized inner product algorithms are both used to screen secondary data in the NHD stage of signal processing. The resulting data set is homogeneous, with respect to the test cell under the null hypothesis, and is used for adaptive weight measurements.
