卫星对地搜索问题研究——搜索理论的新应用

用卫星搜寻海上的未知目标时，由于海洋的面积大，可参照点少，搜寻未知目标难度较大，因此有必要对此展开研究。建立了对地观测卫星对海洋未知目标的搜索模型，同时给出一种评估卫星搜索探测函数的新方法，在此基础上，以一颗载有推扫式CCD相机的低轨小卫星为例，说明如何用该模型指导卫星搜索海域内的未知目标，从而使卫星在有限的观测时间内发现目标的概率最大，为搜索理论在卫星应用上提供了新思路。

Research on Satellite Searching Problem——New Application of Search Theory

Searching unknown position targets in the sea with the help of satellites remains to be a problem by reason of large scale of the sea and few reference points. To overcome these barriers, a model of earth observation satellite searching unknown position targets was constructed in the sea and a novel method was developed evaluating the detection function, so as to achieve the maximum probability of finding the target within limited observation time. Furthermore, an example of a low orbit small satellite with the CCD camera demonstrated the method of searching unknown position targets with the application of this model. This research offered a new way of utilizing search theory in satellite application.
