卫星搜索海上机动目标最优搜索效能分析

Effectiveness Analysis of Searching for Manoeuvring Targets on the Sea by Satellite Based on the Optimum Plan

卫星在搜寻海上机动目标过程中,由于搜索面积大,可参照点少,在一定程度上增加了搜寻目标的难度。文章针对这一问题,在分析卫星搜索海上机动目标过程的基础上,将最优搜索理论应用于卫星搜索海上机动目标的过程中,建立了卫星搜索海上机动目标的随机搜索发现概率模型、离散搜索最优模型及其对应的发现概率模型,并通过计算仿真证明了搜索方法的有效性。该搜索方法对提高卫星搜索海上机动目标的效率有一定的参考。

Searching Manoeuvring Targets on the sea with the satellites remains to be a problem by reason of large scale of sea and few references points.To overcome these barriers,on the basis of analysing the process of searching for the manoeuvring targets on the sea by satellites,the optimal searching theory is used to the process,and then set the optimum plan model of the discrete searching and the model of probability of finding targets which is demonstrated through example.And the above theory and methods will somewhat provide us a reference to provide the efficiency of satellite searching.
