Abstract:
A novel knowledge-aided processing scheme is proposed for use in Ground Moving Target Indication (GMTI) operation to be operated in real time on airborne SAR/GMTI sensors. The proposed approach is based on the Σ-Δ Post-Doppler Space-Time Adaptive Processing (STAP) algorithm and makes use of a priori knowledge sources as well as instantaneous sensor data in order to improve detection performance in nonhomogeneous interference environments. The algorithm is tested with actual radar data obtained during flight trials and the results of both the traditional and the knowledge aided methods are presented and compared.
