Abstract
Abstract Aiming at the current methods of range delay and azimuth Doppler frequency modulation used in deceptive jamming, this paper proposes a two-dimensional mixed baseline method for deception jamming recognition based on multi-input multi-output synthetic aperture radar (MIMO-SAR). In this paper, on the basis of MIMO-SAR phase coding method which makes the multi-channel signal orthogonal, we propose to detect the deceptive jamming phenomenon by employing multi-dimensional phase information. Among them, the intersection-orbit interferometric phase is used to identify the range-delay deception jamming, and the along-orbit interferometric phase is used to identify the azimuth Doppler frequency modulation deception jamming. The combination of the two methods can identify two-dimensional deception jamming. Experimental results demonstrate the validity of our method.
