摘? ?要：毫米波雷達具有更接近小粒子尺度的短波長，更適合用來探測弱云，是云三維精細結構的重要探測工具。但是相比于厘米波段，毫米波信號在云雨天氣的傳輸過程中更易受到云、雨、大氣氣體的衰減，導致回波面積的減小，毫米波雷達觀測值要小于實際值，因此在毫米波測云雷達的探測與反演研究中需要考慮大氣衰減的影響。根據逐庫訂正法，利用JAVA與MATLAB混合編程技術，設計了毫米波測云雷達回波衰減訂正軟件。該軟件集合了JAVA和Matlab兩者的優點，在高速計算的同時兼顧了可視化。

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.
