Abstract
This paper introduces the formulation of the transmit-waveform-shaped noise jammer (TWS-NJ) as an electronic attack (EA) or noise interference method into space-time adaptive processing (STAP). Monte Carlo simulation reveals a substantial impact on target detection, particularly when the TWS-NJ is co-located with the target in the same spatial cell. Comparative analyses against conventional noise interference like the broadband noise jammer (BB-NJ) underline the superior performance of the TWS-NJ in degrading target detection, especially in the absence of electronic protection (EP) implementation. The study highlights the significance of considering both waveform characteristics and spatial locations of noise interferences when assessing their impact on detection performance. Moreover, the study demonstrates that with electronic support (ES) and an accurate noise interference covariance matrix estimate, the generalized matched filter (GMF) emerges as a highly effective STAP EP technique for mitigating adaptive shaped interference.
