本文利用气象雷达的测量结果考虑到雨的不均匀结构,得出了与频率无关的降雨率剖面模式。频率在10GHz以上通过地空路径的降雨总衰减可以很方便地用这个模式进行计算,文章还计算了12GHz、20GHz和30GHz,仰角分别为60°、45°及23°的三种倾斜路径总降雨衰减,并与我们自己的实验结果以及其他作者提供的实验结果进行比较,结果符合得很好。
In this paper, taking into account the uneven structure of the rain, the results of the meteorological radars are obtained, and the frequency-independent rainfall rate profile model is obtained. The total rainfall attenuation over the ground-and-air path at frequencies above 10 GHz can be easily calculated using this model. Total rainfall is also calculated for the three oblique paths of 12 GHz, 20 GHz and 30 GHz with elevation angles of 60 °, 45 ° and 23 ° Decay, and in good agreement with our own experimental results and the experimental results provided by other authors.
