作为中国遥感卫星辐射校正场项目的前期准备工作

于1994年6月和1996年9月

利用自行研制的智能型野外双向反射特性地面测量系统——VF921对敦煌辐射校正场地面方向反射特性（BRDF）进行了测量。通过对这两次测量数据的处理和分析

对场地的BRDF特性进行了分析和评价。同时

对于整个测量系统和数据获取与处理中还存在的问题进行了讨论。

As a preliminary step in the programm of radiative calibration site of remote sensing satellite of China

we measured the bidirectional reflectance distribution features （BRDF） of Dunhuang Site’s surface twice in June

1994 and September

1996 by using an intelligent instrument-VF921

a system made by ourselves for measuring the bidirectional reflectant properties. Through the datum processing and analyzing of these measurements

this paper evaluated the BRDF of the Site. Meanwhile

the paper also analyzed and discussed the problems within the measurement system and the datum processing methods.
