摘　　要：在传统的遥感理论中,通常是将物体都看成了朗伯体,这就忽略了物体的本身的特性—二向反射特性。南疆红枣产量巨大,迫切需要近地面遥感技术进行对枣园进行监测。本文利用二向反射光度计对南疆的骏枣进行了二向反射特性研究。结果表明在相对方位角180°,入射天顶角等于探测天顶角区域,红枣的反射率达到峰值。而且随着光源入射角的不断增大,红枣表面所产生的镜面反射也逐渐增大,直至布鲁斯特角。本文为今后南疆的枣园监测提供了参考。In the traditional remote sensing theory, the object is usually regarded as a lambert body, which ignores the property of the object itself -the reflection property.The production of red jujube in Southern Xinjiang is huge.In this paper, the Reflection characteristics of junzao in Southern Xinjiang were studied by means of Bidirectional Reflection photometer.Results show that the relative azimuth Angle 180 °, the incident zenith Angle is equal to the detection of zenith Angle area, red reflectance peak.With the increase of the incident Angle of the light source, the specular reflection on the surface of the jujube gradually increases until brewster Angle.This paper provides a reference for the future monitoring of jujube garden in Southern Xinjiang.
