Abstract

The invention discloses an underwater self-adaptive maneuvering target rapid tracking method, which comprises the following steps: analyzing the motion situation of a target, tracking the target in real time by using a nonlinear Kalman filter, solving the motion state parameters of the target, and enabling an observation platform to adaptively track the target according to the estimated motion parameters.

Description

technical field [0001] The invention belongs to the field of fast tracking of a maneuvering target in an underwater environment, and in particular relates to a rapid tracking and tracking method of an underwater self-adaptive maneuvering target. Background technique [0002] Underwater acoustic equipment based on underwater acoustic detection technology is the important eyes and ears of our navy's underwater combat, and it is also the most effective means of underwater target tracking. For underwater target tracking system, sonar is its most important component. According to the working mode of the target tracking system, the underwater sonar target tracking system is mainly divided into active tracking mode, passive tracking mode and active and passive joint tracking mode. The active sonar target tracking system means that the sonar actively sends out pulse waves or continuous waves, and receives echoes reflected from underwater or surface targets, and finally calculates t...
