研究發現，海雜波的強度在統計上符合韋布爾分佈。 -
The one is brought by meeting and overlapping of mixed and high level trough moving eastward cloud systems whose echo depth is about 12 km, and the horizontal distance is within 10 ~ 20km and the intensity is up to about 50dbz
混合雲團與東移的高空槽雲系相遇並疊置的大到暴雨過程，鑲嵌于回波中的對流單體是造成強降水的直接系統，其尺度只有10 ~ 20km 。 -
This radar database system fits for china ' s radar network using object - oriented programming design method, recording some important parameters of radar data : the longitude, latitude of radar station, radar type, radar wavelength, radar data format, weather kind ( kind of intensity radar echo, schema of velocity radar, echo shape ) embodying in the radar data, etc. it also records the weather course information embodying in a series of relational radar data : the beginning time of weather course, the ending time of weather course, weather type, etc and the disk information, including recording time, recording contents, recording data number and weather type, etc. above all, this system realizes some basic operational processing : adding, deletion, updating, query of records and also some assistant functions : exportation, data transformation, displaying, backing up of data
該數據庫系統採用面向對象程序設計方法，用visualc + + 6 . 0作為應用程序的前端開發工具，用microsoftaccess2000做數據庫，不僅實現了對雷達基數據信息的一些基本操作：記錄信息添加、刪除、修改、查詢，還實現了處理、分析雷達基數據所需的一些操作：數據導出，數據格式轉換、數據回顯（圖像方式和動畫方式） 、數據壓縮、備份等，另外針對日前雷達臺站存儲雷達數據的現狀，還實現了對存儲光盤的管理。 -
Based on the above, the paper analyses the echo model of sar moving target and the impact that caused by the velocity of moving target in sar image with imaging theory. then the paper gives the intensity image of the real part of the echo for both static and moving targets, and the paper gives their imaging picture generated by r - d algorithm as well
在此基礎上，本文推導出了運動點目標的回波模型，並結合成像原理分析了運動目標速度對sar圖像的影響，最後給出了靜、動目標回波的實部灰度圖及其r - d演算法成像圖，並進行了分析和比較。
