| 摘 要： | 地物微波反射率是卫星气象和雷达气象的重要信息,需要进行实验室内模拟自然的实验研究。只有解决近场反射过程中的微波传输问题,才能研究有据,测量准确。本文研究了近场反射过程中微波传输的特性和近场测量转换至远场情况的订正方法,在实验室内测量了标准反射面的反射特性,用实验证明了本文提出的订正方法的有效性。本文得到了理论与实验一致的结果。因此,这种近场订正的方法是实用的。

| Abstract: | Reflectivity of ground truth is an important information of remote sensing.Experiments in lab are carried to study characteristics of microwave reflectivity in order to provide guidance for practice.In the first,how to transform the lab near field data to the natural far field must be solved.In this work,microwave reflectivity in the near field and retrieval of the near field data to the far field condition are studied theoretically.In the last,the correction is checked experimentally by microwave reflectometer. |
