定标是星载遥感设备的重要组成部分。文章介始了我国海洋卫星星载微波散射计的定标概念、主要误差来源及拟采用的定标策略与方案。重点提出内定标信号源的两种实现方法,并通过比较的方法介绍了两种定标信号源的特点。
Calibration is an important part of spaceborne remote sensing equipment. The article begins with the calibration concept, the main sources of error and the calibration strategy and scheme to be adopted in China’s marine satellite microwave-borne microwave scatterometer. Two kinds of implementation methods of internal calibration signal source are put forward emphatically, and the characteristics of the two kinds of calibration signal source are introduced through the comparison method.
