Abstract :
This paper presents some new results on spatial adaptive pre-suppression (SAPS) of jammers for STAP-based airborne surveillance radars. The main contributions are: (1) two SAPS algorithms with a double sideband (DSB) technique for the acquisition of jammer-only data, and (2) an approximate formula for determining the requirement on the sidelobe level of the sum (Σ)-beam for the class of sum-difference beam (ΣΔ)-STAP with SAPS. A performance evaluation shows that ΣΔ-STAP with the suggested DSB algorithms for SAPS performs well in the presence of both clutter and jammers, while the required antenna sidelobe level is practically reasonable
