A Modulation Based Approach to Wideband-STAP (Postprint)

Abstract

In this paper, a new method for processing wideband radar data is presented. To perform the full degree of freedom wideband processing, 3-D space-time adaptive processing (STAP) needs to be implemented, which involves intense computational burden. One approach in this case is to do subband STAP processing and combine these outputs. In this paper, instead of traditional subband processing, the incoming wideband data signal is modulated by multiple carriers, combined, and filtered prior to processing using narrowband STAP. This method offers a significant decrease in computation burden compared to the subband method.
