“…Although Monte Carlo method has the advantages of simple concept and easy implementation, its calculation accuracy heavily depends on the number of simulations, which cannot meet the real-time requirements of the calculation. It is more suitable for theoretical research [34] rather than actual combat applications. In contrast, the analytic method can directly calculate the encounter probability by establishing a mathematical model.…”

“…However, the encounter model is limited as it is solely based on geometric relations, without considering the initial course, the maneuvering ability as well as rotational angular velocity error, which has limitations to some extent. Literature [34] takes the electromagnetic launched anti-torpedo torpedo as the research object. The mean square deviation of the heading angle is obtained by the implicit function differential method, and the capture probability is obtained by integration.…”

Supercavitating vehicles have received significant attention in military applications due to their high underwater speed. This paper aims to establish an analytical model of the encounter probability between a supercavitating vehicle and its target in two modes: straight-running mode (SRM) and turningstraight-running mode (TSRM), providing the basis for combat decision-making. We propose a mathematical model for the supercavitating vehicle to encounter the target in SRS and TSRS. An improved particle swarm optimization (PSO) algorithm based on local best topology with a penalty function is introduced to plan the TSRM path of the supercavitating vehicle. The particle swarm position is updated by using Cauchy and Gaussian distributions. The Monte Carlo simulation method considering the target scale is employed to determine the judgement indexes of the encounter probability analytical models in SRS and TSRS through statistical analysis. Based on the law of error propagation, the analytical models of judgement index variances in the two modes are derived by using the implicit function differential method, and the integral interval of the analytical models of encounter probability is obtained according to the relative motion of the supercavitating vehicle and target. Monte Carlo simulation and hypothesis testing are utilized to verify the accuracy and feasibility of the encounter probability analytical models between the supercavitating vehicle and the target.INDEX TERMS Supercavitating vehicle, encounter probability, path planning, Monte Carlo method, the law of error propagation.

Aiming at the problem of underwater attack and defense in typical situations, a mathematical model of three-party attack and defense problem composed of torpedo, submarines and anti-torpedo torpedo is established. Under the condition of considering three-party game confrontation, the three-party game problem is transformed into the pursuit and escape game problem between the submarine and torpedo, and the interception and evasion game problem between the submarine launched ATT and the torpedo. Based on the optimal control theory and differential game theory, the three-party optimal game problem is studied, and the three-party game performance evaluation function is designed based on the optimal performance of the two parties of pursuit and escape and the two parties of interception and evasion. According to the optimal necessary condition of the bilateral extremum, the strategy of pursuing, escaping, blocking and avoiding in the three-party game is deduced. The effectiveness of the game strategy designed in the underwater attack and defense process is verified by simulations. The results show that the game strategy can improve the effects of submarine escape, anti-torpedo torpedo interception and torpedo attack.
