Analytic Method for Calculating Probability of Direct Torpedo

According to the traditional statistical calculation method of torpedo found probability with large computation,from the analysis of target distribution and torpedo dispersion error,the various target elements and torpedo advance angle error propagation,using the error transmission theorem established the analytical calculation model of direct torpedo found probability,by comparing with the traditional Monte Carlo statistic method,verifying the correctness of the analytical model,laid the foundation for real time prediction of torpedo found probability and real time optimization of torpedo control parameters.
