Abstract

Submarine and decoys exist under the decoy jamming environment. Traditional trajectory guide methods of the torpedo couldn't guarantee the need for identifying and attack requires simultaneously on multiple targets. The torpedo guidance method framework of the multi-decoy environment is suggested. Founding on the theory of the artificial potential field, a multi-objective guidance method is also provided. The method combines the target plausibility probability and the guiding direction systematically which can consider all targets' effect to the torpedo. Firstly, the tract target is decided using the probability of all targets and then the traction attention rate of the target is computed; next, the repulsion in artificial potential field is improved and the concept of attracting attention is posed, the attracting attention and guiding attention rate of all other targets can be got; finally, the angular velocity of the torpedo with the limitation of its maneuvering capability is calculated. Simulation using static target piles and moving objects demonstrated that, the method cannot only guarantee the attack of the maximum probability target and at the same time can give consideration to detection and recognition of as much as possible targets. It can improve the accuracy of the attack significantly.
