Improved Azimuth and Pre-point Guidance Methods for Wire-guidance Torpedo

The guidance effect of the typical azimuth and pre-point wire-guidance method is unsatisfactory because of the limited guidance principle and calculation precision of target parameter. In this paper, the precision of azimuth guidance is raised by introducing target motion parameter to the azimuth guidance method, and the influence of distance error on guidance is reduced by correcting and adaptively adjusting target distance in pre-point guidance method. The simulation results verify the improvement of wire-guidance precision of the two methods.
