Detection Performance of Enhanced Electronic Protection Mitigation In Space-Time Adaptive Processing Against Adaptive Shaped Interference

This study introduces adaptive shaped interference such as the transmit waveform shaped noise jammer (TWS-NJ) into space-time adaptive processing (STAP) and assesses its impact on detection performance. Results from simulation demonstrate that the TWS-NJ has superior noise jamming performance over conventional noise jammer like the broadband noise jammer and causes a large degradation in detection performance. This degradation is even more apparent when the noise jammer is located with the target in the same spatial cell. The study then evaluates the effectiveness of the generalized matched filter (GMF) in mitigating these advanced interferences. Results show that the GMF exhibit superior performance against TWS-NJ when aided with an accurate estimate of the noise jammer covariance matrix, highlighting its efficacy in enhancing electronic protection for STAP.
