本文介绍了在法国阿维尼翁国家农学研究所的陆地试验场使用EMIRAD L波段极化辐射计进行的极化方位角特征的现场测量的初步结果。进行了方位角180度的扫描，以确定斯托克斯矢量对看向的最终依赖性。结果表明，无论是裸露的土壤还是覆盖作物的地表，都有明显的特征，并且观测到了超过10K的变化。
This paper describes preliminary results from field measurements of polarimetric azimuth signatures with the EMIRAD L-band polarimetric radiometer, performed over a land test site at the Institut National de la Recherche Agronomique in Avignon, France. Scans of 180 degrees in azimuth were carried out in order to identify an eventual dependence of the Stokes vector on the look-direction. Results indicate a clear signature, for bare soil as well as for the crop-covered surface, and variations of more than 10 K are observed.
