Abstract:Based on the federal filter idea, the kinds of information from airborne data-link, photoelectric sensor and radar are fused to solve the problem that radar is liable to suffer from deception jamming in the process of tracking. First of all, measurement feature of the radar is analyzed, which is disturbed by using the different deception jamming methods, and the detection method of airborne multi-sensor jamming is studied. Combining with interacting multiple models, time unification, information equivalence transformation, and information distribution, this paper utilizes the federated filter for building an airborne multi-sensor anti-deception-jamming information fusion algorithm. The result of the computer simulation shows that the deception-jamming to radar can be detected, and the true target of radar- tracking can be ensured effectively by adopting the algorithm.
