Underwater sound multi-target guiding method based on artificial potential field method

Abstract

The invention relates to an underground sound multi-target guiding method based on an artificial potential field method. For the condition that an acoustic decoy (a false target) exists in a complicated underwater environment, the artificial potential field method is applied to underwater attack weapon multi-target guiding, a traction speed VA, an attracting speed VA and a guiding speed VG are combined, so that the speed vector V<next> at a next moment of an underwater attack weapon is obtained, the course at the next moment of the underwater attack weapon is calculated, the course angular speed at the next moment of the underwater attack weapon is calculated, and then target guiding is conducted. By the adoption of the underground sound multi-target guiding method, it is guaranteed that as many as possible targets which are not completely checked are detected, and the identification effects on the targets are guaranteed; on the premise that it is guaranteed that the attack weapon moves to the target with the highest plausible probability, the attack weapon is close to other targets to the greatest extent, and therefore the targets are effectively identified in the guiding process; the minimum distance between each target and the underwater attack weapon is shorter than an effective identification distance, and it means that all the targets can be effectively identified.

Description

technical field [0001] The invention belongs to an underwater acoustic multi-target guidance method, in particular to an underwater acoustic multi-target guidance method based on an artificial potential field method. Background technique [0002] Traditional underwater attack vehicles use tracking method and fixed advance angle method as guidance methods (Zhang Yuwen, "Ballistic and Ballistic Design of Underwater Attack Vehicle", 1999), according to the orientation of the target relative to the weapon, only the most likely probability target to attack. The tracking method and the fixed advance angle method are simple in structure and easy to implement. With the increasingly complex environment of modern underwater acoustic countermeasures, targets will release acoustic decoys to interfere with offensive weapons. At the same time, it needs to combine the attribute information of the target for target recognition. The tracking method and the fixed advance angle method are a...

AI Technical Summary

Problems solved by technology

The tracking method and the fixed advance angle method are aimed at a single target and do not consider how to accurately obtain the attribute information of the target. They cannot guarantee the identification of other targets during the guidance process. Their guidance trajectory is not suitable for attacks in complex confrontation environments. There is no similar literature on the problem of multi-target strike ballistics
