摘要
概要评述可见近红外、主/被动微波遥感技术监测海冰密集度的基本原理、算法及其优缺点。着重介绍和讨论被动微波传感器SMMR和SMM/I遥感图像混合像元内海冰总密集度,一年海冰及多年海冰密集度的NA SA算法及其天气滤波器。
In this paper a brief comment on the basic principle, algorithm and advantage/drawback of monitoring sea ice concentration using remote sensing technique in visible-infrared, passive and active microwave is made. Especially, the NASA team algorithm and its weather filter for monitoring total, first-year and multi-year sea ice concentration in each mixed pixel, which are shown on the remote sensing image by using passive microwave sensors SMMR or SSM/I, are introduced and discussed in detailed.
