Acoustic homing torpedo favorable advance angle correction method based on Monte Carlo method and centroid method

Abstract

The invention relates to an acoustic homing torpedo favorable advance angle correction method based on a Monte Carlo method and a centroid method, and belongs to the technical field of torpedo navigation and guidance. According to the method, a Monte Carlo method is utilized to obtain a correction method for the optimal correction parameter of the favorable advance angle with maneuvering avoidance of the target parameter under a specific condition, and the capture probability of the sound homing torpedo can be improved when the target is subjected to maneuvering avoidance by correcting the favorable advance angle. The method solves the problem that the capture probability is low when the acoustic homing torpedo is launched according to the original favorable advance angle during target maneuvering avoidance, can be used for determining the launching angle of the torpedo during target maneuvering avoidance, and provides a certain reference for a torpedo launching strategy.

Description

technical field [0001] The invention belongs to the technical field of torpedo navigation and guidance, in particular to an acoustic self-guiding torpedo favorable advance angle correction method based on a Monte Carlo method and a centroid method. Background technique [0002] The determination of the favorable advance angle of the homing torpedo is an important part of the torpedo navigation and guidance. When other launching conditions are certain, the target acquisition probability is a function of the advance angle. Under certain launching conditions, the homing torpedo has the highest probability of capturing the target The advance angle is called the favorable advance angle. When launching a self-guiding torpedo, the more accurate the calculation method of the favorable advance angle, the higher the probability of the torpedo capturing the target, which can effectively improve the combat effectiveness of the self-guiding torpedo, and can also provide better reference ...
