星载遥感器在飞行时的绝对辐射定标方法

Methods for the In-flight Absolute Radiation Calibration of Space-borne Remote Sensors

20世纪70年代末80年代初,以美国Slater教授为代表的一批科学家提出了卫星飞行中利用辐射校正场对卫星遥感器进行辐射定标的方法。这是一种行之有效和很有前途的方法。 文章首先简介国内外的发展情况,然后阐述辐射定标原理、流程以及几种定标方法。

From the end of the 1970's to the beginning of the 1980's. Some American scientists, whose leading exponent is professor Slater, proposed a method for the in-flight absolute radiometric calibration of satellite remote sensors by means of the radiation calibration field . It is a feasible, valid and very hopeful method. In this paper,the national and international conditions under development are briefly introduced . The principle,technological process and several methods for the in-flight radiometric calibration are described.
