[0026]In order to make the objectives, technical solutions and advantages of the present invention clearer and more comprehensible, the present invention will be further described in detail below in conjunction with the accompanying drawings and technical solutions.
[0027]In the tracking of maneuvering targets, in order to satisfy the full-range trajectory tracking of ballistic missiles, see thefigure 1 As shown, a method for ballistic missile trajectory estimation based on improved autonomous multi-model is provided, including the following contents:
[0028]S101. Construct a motion model set for full-range trajectory estimation, the model set includes at least: an accurate dynamics sub-model for non-motorized section detection and a three-dimensional current statistical sub-model for maneuver section detection;
[0029]S102. According to the change of the movement state of the missile in the maneuver detection, the hard decision is adopted to switch the sub-model by setting the probabili...
