Research on the Compound Jamming Method against FDA-MIMO Beamforming

Abstract

Frequency diverse array multiple-input multiple-output (FDA-MIMO) radar solves the problem of angle pointing and range pointing during beam transmission due to its unique range-angle dimension dependent, which gives it good characteristics against main lobe deceptive jamming. Moreover, the current single range dimension deceptive jamming is easy to be identified and cannot form an effective jamming effect on FDA-MIMO radar. To address this problem, this paper proposes a compound jamming method of suppression and range deceptive against FDA-MIMO beamforming. Compared with the traditional deceptive jamming method, this method can reasonably utilize the beam gain, and minimum variance distortionless response (MVDR) adaptive beamforming cannot significantly reduce the power of the jamming, thus avoiding the jamming being weakened at the beamforming level, and the jamming may appear in different range bins, causing significant suppression and range deceptive compound jamming effects on FDA-MIMO radar in the range dimension. The simulation verified that the compound jamming method can effectively interfere with the FDA-MIMO radar at the beam-forming level, and the jamming effect is good.

Improved MUSIC Method against Range Dimension Deceptive Jamming Based on FDA-MIMO

“…The deceptive interference signal flow is corrected in [22,23], and a new range dimension deceptive interference method is proposed. Yang Chen [24] proposed a composite interference method of suppression and range deception for FDA-MIMO beamforming. References [25,26] proposed a method based on subarray and meshless compressed sensing for evaluating the range parameters information and angle parameters information based on the FDA radar.…”
