Increasing Secondary Data or Enhanced Adaptive Displaced Phase Centered Antenna Approaches. Volume I

Abstract : A study of space-time adaptive processing in nonhomogeneous environments is presented. The results produced are logically organized as investigations into three different but related topics. The first topic can be summarized as an investigation of the performance of partially adaptive space-time adaptive processing schemes using measured (MCARM) data. The second topic considers the development of a new set of space-time processing algorithms, which use prior knowledge to reduce the number of parameters, which need to be adapted. The new schemes were tested using MCARM data. The final topic provides analytical realistic cases where the reference or training data may have different statistics from the data in the cell under test. Such equations have not yet appeared in the literature and they are useful for understanding the performance of space-time adaptive processing (STAP) schemes when they are tested with MCARM data.
