Embodiment Construction
[0083] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. Based on the implementation manners in the present invention, all other implementation manners obtained by persons of ordinary skill in the art without making creative efforts belong to the scope of protection of the present invention.
[0084] The extended truncated unscented Kalman filter ETUKF of the present invention estimates the state of the target at a certain moment from a series of incomplete and noise-containing target observation vectors. The basic theory of the present invention's extended truncated unscented Kalman filter method is specifically as follows:
[0085] Suppose the state vector of the target at time k is x k =[a k T ,b k T ] T...
