摘要

摘要: 解析法和模拟法是计算声自导鱼雷发现概率的常用方法, 解析法速度较快, 但只适用于部分参数误差类型, 模拟法适用于所有参数误差类型, 但计算效率较低。针对此, 提出一种解析法与模拟法相结合的发现概率计算方法, 首先基于模拟法的思想求解参数遮盖区间, 然后在此基础上利用解析法计算发现概率, 在保证精度的同时明显提高了计算效率, 最后通过仿真验证所提算法的有效性。

Abstract: The analytical method and simulation method are commonly used to calculate the probability of torpedo discovery. The analytical method has a fast speed, but it is only applicable to some parameter error types. The simulation method is applicable to all parameter error types, but the computational efficiency is low. To address this issue, a discovery probability calculation method combining analytical and simulation methods is proposed. Firstly, the parameter masking interval is solved based on the idea of simulation methods. Then, the discovery probability is calculated using analytical methods, which significantly improves computational efficiency while ensuring accuracy. Finally, the effectiveness of the proposed algorithm is verified through simulation.
