摘要
数字化天气雷达组网拼图系统的建设是气象观测业务发展的趋势和重点。针对不同波长的常规数字化天气雷达和多普勒天气雷达拼图存在的问题 ,在系统介绍数字化天气雷达组网拼图的基本原理和具体算法的基础上 ,采取了 d BZ转换和衰减订正等技术措施 ,较好地解决了多部天气雷达观测回波的可比性、代表性等问题 ,得到了较好的拼图结果。业务实验表明 ,通过采用给定的拼图算法 ,组建由多部不同波长天气雷达组成的天气雷达网是可行的。
Digital weather radar networking and composite imagery is a main trend in the developments of operational meteorological observations. In this paper, the basic principle and detailed algorithm for digital weather radar networking and composite mapping are introduced. Regarding to the existing problems of different wavelength weather radar networking and composite mapping with ordinary digital weather radar and Doppler weather radar, some techniques as dBz transform and attenuation correcting are adopted to solve the problems of compara bility and representability. Experimental results show that the composite image is reasonably good, and it is available for the operational networking and composite mapping for different wavelength digital weather radar.
