利用极限作用距离多层次拒止自航器的方法

A Method of Multilevel Interception of Unmanned Underwater Vehicles Using Limit Acting Distances

摘要:

水下无人自航器是水面舰船自身安全的主要威胁之一。为解决悬浮式拦截装备对水下无人自航器拦截率较低的问题，在原有装备作用距离、射界和威力不变的基础上，提出了利用其最大和最小射程以及最小入水准备时间，进行远场/近场 2 批次拦截的拒止策略。建立了多层次拦截水下无人自航器的数学模型， 采用蒙特卡洛法进行计算机仿真，仿真表明：利用这种拦截策略并配合舰船的规避机动，在 2 次发射间隔内， 可进行装填实现多次拦截，对后舷而来的自航器拦截概率提高到 70%~81%。

Abstract:

Unmanned underwater vehicles（UUVs）pose a significant threat to the safety of surface ships. To address the issue of low interception rates of suspended interception equipment against UUVs，a denial strategy of conducting two batches of interception in the far field and near field is proposed based on the unchanged action range， field of fire，and power of the original equipment，by utilizing its maximum and minimum ranges and minimum water entry preparation time. A mathematical model for multilevel interception of UUVs is established，and computer simulation is conducted using the Monte Carlo method. The simulation results show that by employing this interception strategy in conjunction with the ship's evasive maneuvers，multiple interceptions can be achieved within the interval between two launches，and the interception probability of UUVs approaching from the stern can be increased to 70%~81%.
