Method for resisting infrared surface source decoy interference based on dual-mode coordination

The invention relates to a method for resisting infrared surface source decoy interference based on dual-mode coordination, and belongs to the technical field of missile guidance interference resisting. The method comprises the steps that 1, consecutive frame photographing is conducted on a target through an infrared system on a missile, and whether the target launches interference missiles or notis judged according to photos; 2, the target and all the interference missiles are parsed to serve as candidate target points; 3, whether the candidate target points are suspected points or determined interference points is judged, the suspected points are reserved, and the determined interference points are removed; 4, confidence values of all the suspected points are calculated, and when the confidence values exceed a threshold value N, it is judged that the suspected point is the target; and 5, a radar system is shut down, the infrared system is adopted to continue tracking the target. According to the method, the
