摘要
舰船驶过海面后会形成一条长度可达数千米且持续很长时间的尾迹区,利用尾迹可以实现舰船目标地理位置、运动参数的估计,热红外遥感基于该尾迹图像可实现全天时的舰船监测。目前,舰船尾迹的红外特征研究大都是基于仿真模型进行的,并基于仿真图像建立了尾迹的探测模型,缺乏真实的在轨红外遥感数据验证。文章基于“高分五号”(GF-5)卫星全谱段光谱成像仪红外图像,分析研究目前主要的两种尾迹(V型波和湍流)在短波红外、中波红外和长波红外的特性,为后续的基于红外遥感图像的舰船尾迹检测提供支持。
When the ship sails on the sea,a wake of several kilometers length and long continuous time will appear behind the ship.The geographic position and motion parameter of the ships can be gotten based on the ship wake characterization.The whole day ship detection could be realized based on the thermal infrared shape wave images.The common research method of the thermal infrared ship wave characterization was ship wave modeling.The detection model was build based on the ship wave model.The infrared(short-wave infrared,medium-wave infrared and the long-wave infrared)characterization of the common two kinds of ship wake was analyzed and summarized in this paper.The characterization can provide support for ship wake detection.
