最优化法求Z—Ⅰ关系及其在测定降水量中的精度

DERIVATION OF THE Z-I RELATIONSHIP BY OPTIMIZATION AND THE ACCURACY IN THE QUANTITATIVE RAINFALL MEASUREMENT

本文介绍了用最优化原理求取Z—I关系的新方法,并将求得的最优化Z—I关系式应用于雷达探测单点和区域降水量。结果表明:探测降水量精度可以明显提高。经过检验,表明该关系式具有一定代表性。

This Paper presents a new method for deriving the Z-I relationship by optimization and its application to radar measurement of precipitation amount at single Lacations and over an area, It is found that the accuracy of rainfall measurement can be greatly improved, tests show that the Z-I relationship has wide representativeness.
