    摘要:

    研究了随机运动目标区域持续探测的探测概率描述和计算问题。定义了探测函数及目标存在和探测不成功的联合概率密度函数,推导了基于速度分布密度的搜索方程和基于特征迹线的方程的解。鉴于在搜索理论应用中难以获得时变的速度分布,以及搜索方程精确解的复杂性,提出了基于初始速度分布密度的对随机恒速运动目标的一个近似的搜索方程,给出了探测概率的解,并以直升机吊放声纳的一次探测过程,进行了算例仿真。

    Abstract:

    The probability description and calculation, searching a random moving target in continuous space, persistencedetecting in an immobility space, was studied. First, the detection function and the joint probability density function of tar.get location and loss detection were defined. Then, the search equation based on the velocity distribution and its solutionin a characteristic ray were deduced. Due to the difficulty of obtaining the velocity distribution function with respect to thetime, and the complicacy to get the solution of search equation, an approximate search equation based on initial velocitydistribution function of random moving target with random constant velocity and its probability solution were presented.Simulation samples of detection processes about searching submarine operation used dipping sonar of helicopter were cal.culated.
