Abstract:In order to improve the underwater defense capability of surface ship formation, building an underwater defense equipment system supplemented by surface unmanned vehicle is an important direction of future development. On the basis of summarizing the current situation and development trend of surface unmanned vehicle at home and abroad, this paper analyzes the necessity of the development of unmanned vehicle. Combined with the task requirements of surface ship formation to defend against torpedo attack, the operational use method of surface unmanned vehicle is studied. and simulates, analyzes and evaluates The countermeasure effectiveness is evaluated by simulation. Relevant research results can guide the development and application of surface unmanned vehicle in the field of underwater information countermeasure.
