ABSTRACT
The emphasis in this chapter is on adaptive signal processing to include adaptive array processing and Space Time Adaptive processing (STAP). Adaptive arrays employ phased array antennas to adaptively sense and eliminate unwanted signals entering the radar's Field of View (FOV) while enhancing reception about the desired target returns. For this purpose, adaptive arrays utilize a rather complicated combination of hardware and require demanding levels of software implementation. Through feedback networks, a proper set of complex weights is computed and applied to each channel of the array.
