中文摘要:毫米波雷达具有更接近小粒子尺度的短波长,更适合用来探测弱云,是云三维精细结构的重要探测工具。但是相比于厘米波段,毫米波信号在云雨天气的传输过程中更易受到云、雨、大气气体的衰减,导致回波面积的减小,毫米波雷达观测值要小于实际值,因此在毫米波测云雷达的探测与反演研究中需要考虑大气衰减的影响。根据逐库订正法,利用JAVA与MATLAB混合编程技术,设计了毫米波测云雷达回波衰减订正软件。该软件集合了JAVA和Matlab两者的优点,在高速计算的同时兼顾了可视化。

Design of Millimeter Wave Cloud Radar Echo Attenuation CorrectionSimulation Software Based on JAVA and MATLAB Hybrid
Abstract:Millimeter wave radar has short wavelength that closer to the small particle size,and is more suitable for detecting weak clouds. It is an important detection tool for three-dimensional structure of cloud. Compared to the centimeter wave band,the millimeter wave signal has more attenuation due to cloud,rain and atmospheric gas,which leads to the reduction of the echo area,and the observation value of the millimeter wave radar is less than the actual value. Therefore,the influence of atmospheric attenuation should be considered in detection and date retrieval of the millimeter wave radar. In this paper,a correction software of echo attenuation at millimeter wave radar is designed based on the method of JAVA and MATLAB mixed programming technology. The software combines the advantages of JAVA and Matlab,and takes account of visualization in high-speed computing.
