Embodiment Construction
[0040] The equivalent evaluation factors selected by the present invention are mainly parameters that can be directly obtained in the infrared system to characterize the flight state of the target. For example, the distance equivalent factor can be characterized by the gray value of the target in the infrared system, and the radial velocity equivalent factor can be characterized by the The gray scale change rate of the target in the system can be represented, the tangential velocity can be represented by the moving speed of the target on the image plane in the infrared system, and the high-low angle equivalent factor can be represented by the position information of the target in the infrared system on the image plane. At the same time, in order to better distinguish each target, the threat membership function of different equivalent evaluation factors is different, and according to the difference of equivalent evaluation factors, the weight of each index is determined by the le...
