A Measurement Matrix-Based Deceptive Jamming Suppression Method for Compressive Sensing Radar

The problem of detection performance degradation caused by digital radio frequency memory(DRFM) repeat-back jamming in compressive sensing radar(CSR) is investigated in this paper. Then we present a deceptive jamming suppression method based on a structured measurement matrix. Specific initial phases are added in each transmitted pulse to make the CSR be able to distinguish the jamming pulses firstly. Then a structured measurement matrix is devised to demodulate the additive initial phase of each received pulse and accumulate the target's echo without integrating the deceptive jamming. Compared with the existed typical target detection methods in CSR, the proposed method achieve more accurate targets estimation by suppressing the false target caused by deceptive jamming. Numerical results demonstrate the superior performance of the proposed deceptive jamming suppression method.
