A Vertical Hit Method for Striking the Middle of a Large Undersea Vehicle

Due to the random drift of the target aiming point of the detection system on large undersea vehicles, high-speed attack-type unmanned undersea vehicles(UUVs) often cross the front and rear sides of large undersea vehicles vertically in engineering applications, resulting in target miss. To address the above issues, this article proposed a new vertical hit guidance method that utilized multi-cycle data from the detection system to achieve vertical hits in the middle of a large undersea vehicle. In addition, statistical simulation was conducted. The simulation results show that this method has a relatively low sensitivity to guidance parameters and strong adaptability to the relative position of UUVs and the target vehicle. It can meet the requirements of vertical hit engineering under the existing guidance parameter accuracy requirements. When the hit location is considered, the middle of the large undersea vehicle can be hit vertically, and there is a significant increase in the probability of vertical hit. The method proposed in the article is reasonable and feasible and can improve the damage effect on large undersea vehicles.
