A Suppression Technique For Deception Jamming in Multi-static Radar System Based on Multi-dimensional Information Association

 to counter range-velocity compound deception jamming, a suppression technique based on multi-dimensional information association has been proposed in this paper. First, the normal signal processing procedures are implemented in each receiver to extract the multi-dimensional information matrix of the true and the false targets; In the next, the identification process in amplitude dimension is implemented in fusion center based on the statistical difference of amplitude of the true and the false targets; Then, on account of the Doppler diversity the true target possesses, the identification processes in Doppler dimension is also implemented; Finally, according to the spatial homology, the identification process in range dimension is performed, in which the false targets are discriminated completely and the localization of the true target is realized simultaneously. Through the simulation, it is demonstrated that the proposed technique can suppress the compound deception jamming efficiently and the true target can be located precisely while the high identification rate of the true target can also be maintained.
