摘要
雨强,是无线通信电路设计中必不可少的参数.目前,降雨测量主要利用布设在测量区域的翻斗式或虹吸式雨量计直接测量.在一些人烟稀少的地区,雨量计无法布设,降雨测量无法进行.针对翻斗式或虹吸式雨量计测量降雨的这一缺点,研究了利用地基微波辐射计遥感雨区云层光学厚度来推算雨区降雨量的方法,并给出了一些用该方法测量本地降雨强度的试验数据,对该法的可行性和可靠性进行验证.
Rainfall intensity is a very important parameter in design of the wireless communieation system. At present, the tipping-- bucket rain recorder and the siphon rainfall recorder laid in the region are most used in measuring rainfall. But, in some sparsely--populated areas, and the rain gauge can not be laid, and the rainfall can not be measured. In this paper, for the shortcoming of the tipping-- bucket rain recorder and the siphon rainfall recorder, an applied method on measuring rainfall is studied. Adopting this method, the rainfall of the rain region can be estimated through remote sensing the uptical depth of the rain region by ground--based microwave radiometer. The typical experimental results are given in this paper also.
