Embodiment Construction
[0082] 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.
[0083] The Truncated Quadrature Kalman Filtering (TQKF) of the present invention estimates the state of the target at a certain moment from a series of incomplete and noisy target observation vectors. The truncated integral Kalman filtering method of the present invention is aimed at the target tracking problem in the passive sensor array, and the corresponding system model of the present invention and the basic theory of th...
