Electronic Protection Mitigation Techniques Against Transmit Waveform Shaped Noise Jammers

In this paper, we develop electronic protection (EP) receiver techniques to mitigate the false alarm and detection effects generated by transmit waveform shaped noise jammers (TWS-NJ). Unlike traditional wideband NJ (WB-NJ) and narrowband NJ (NB-NJ) that produce spectral densities almost uniformly distributed across their respective bandwidths, a TWS-NJ assumes apriori knowledge of signal spectral shape, thereby utilizing waveform’s dominant bands in generating jammer noise. For illustration in this paper, we utilize the basic rectangular and Hamming pulses as transmit waveforms to evaluate the detection performance effects of the TWS-NJ waveforms. The bandwidths of the TWS-NJs are parameterized to reflect the effect of practical narrowband constraints. The performance effect of various jammers, including TWS eigenjammer, on detection performance is also investigated. To mitigate these jammers, we develop a generalized EP matched filter for this family of jammers and evaluate performance improvement.
