As one of the three factors for multiangular remote sensing, directionality of the emissivity
has an important effect on measurements. This paper puts forward one method to measure
the directional emissivity of objects. According to this method, one new instrument is
developed. The instrument then is applied to measure some types of ground objects and
samples. This paper first describes the method and discusses several questions during the
measuring process. Data of ground objects and samples are processed and analyzed�…
