Mainlobe multiple false targets deceptive jamming suppression via joint transmit-receive design

A method for suppressing mainlobe multiple false targets deceptive jamming using joint transmit-receive design is proposed in this paper. We utilize multiple-input multiple-output (MIMO) radar waveform design at the transmitting end and employ element-pulse coding (EPC) to modulate the received signal mixing matrix, thereby enhancing the blind separability between the target and jamming. The receiving end adopts blind source extraction (BSE) technology improved by blind source separation (BSS) for processing. By formulating an appropriate optimization model and employing the dynamic superior-inferior subgroup particle swarm optimizer algorithm, the optimal extraction vector for the target echo is obtained to achieve jamming suppression. This method combines the blind signal processing theory at the receiving end with the waveform design theory at the transmitting end, thereby utilizing complementary advantages. The numerical results demonstrate that the proposed method offers a spectrum of performance enhancements over conventional approaches, which are dependent exclusively on either the receiving or transmitting terminal.
