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 interceptions in the far field and near field was 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 multi-level interception of UUVs was established, and computer simulation was 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%.
