摘要

摘要: 光电侦察吊舱对海搜索方式与搜索范围是直升机对海搜索效率与搜索力配置研究的基础。基于直升机及其光电侦察吊舱的性能特点，提出了直升机对海搜索的两种基本搜索方式和覆盖面积；建立了直升机搜索面积计算模型，为直升机系统采用不同的搜索方式进行搜索时计算其搜索效率和搜索力的配置提供了决策依据。为了易于搜索区域发现感兴趣的目标，同时介绍了针对扫描搜索区域图像拼接的处理方法。

Abstract: The search efficiency of a sea target helicopter can be studied based on the searching method and search width of the optical recon pod of the helicopter. According to the characteristic performance of the optical recon pod and helicopter, two basic methods of searching and covering square are proposed for the helicopter to search the sea target. According to the developed search covering square, the commander can determine how to configure the recourses to attain the optimal efficiency. In addition, the processing method for image stitching for the scanned search area is introduced to identify the target of interest in the easy search area.
