摘要：
The main-lobe deceptive jamming is located in the same beam width as the target does, which seriously affects the detection and parameter estimation of the real target. To solve this problem, a method to suppress the main-lobe deceptive jamming is proposed based on the frequency diversity array multiple input multiple output (FDA-MIMO) radar. The main breakthrough of the proposal is that when the angles of the jamming and the target are exactly identical, the distance-angle 2D dependence of the antenna pattern of the FDA-MIMO radar is available. Further, the blind source separation (BSS) algorithm based on the maximum signal to noise ratio (MSNR) is applied to separate the deceptive jamming from the target in different channels, so as to achieve the purpose of jamming suppression. This method does not need the prior information of the distance and the angle of the target. The simulation results verify the effectiveness of the proposed algorithm, and when the jamming to noise ratio (JNR) is 80 dB, the correct detection probability of the target is about 0.98. © 2020, Editorial Office of Systems Engineering and Electronics.
