| 以探雷声呐对目标的累积探测概率计算模型为主要研究对象。以累积探测概率的研究作为效能分析的基础,针对发现概率定义不准确的问题对它提出了新的定义,从而更好地实现对某次搜索过程中探雷声呐发现目标能力大小的仿真计算。通过对探雷声呐工作原理和工作过程的分析研究,将连续多次探测到目标定义为发现目标一次的声呐操作过程与离散的(λ, σ)过程模型相结合,在经典模型理论的基础上提出了适用于探雷声呐的累积探测概率计算模型。仿真结果表明,该计算模型实现了对探雷声呐发现目标能力大小的量化分析,为探雷声呐的作战使用与指挥决策提供了理论依据。 |

| The article takes the cumulative detection probability of the mine-detection sonar target as the main research object. With the cumulative detection probability as the basis of performance analysis, a new definition of detection probability is presented, because the past definition was not accurate, to realize the better simulation calculation for the ability of mine-detection sonar in finding a target during a certain search process. Through the analysis of sonar working principle and process, the detected target is defined as the target that has been seen many times continuously in sonar operation process. Then, combining the target detection defined above with the discrete (λ, σ) process, the paper puts forward the simulation model of cumulative detection probability which is suitable for mine detection on the basis of classical model theory. The results of the simulation indicate that this method can realize quantitative analysis of the sonar ability in finding a target, and offer the theoretical basis for the mine-detection sonar operation and command decision-making. |
