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。 -
Popular automotive anticollision radar is required to measure the velocity and angle of its targets as well as range. therefore, the short - wavelength high - resolution millimeter wave is used, measuring range and velocity through fmcw scheme, measuring angle through multi - beam scanning
通行的汽車防撞雷達採用了波長短、測量精度高的毫米波，以調頻連續波制式測量距離和速度，以多波束掃描的方式測量角度。 -
Over - the - horizon radar ’ s beam - frequency is high frequency band and its wavelength is so long that the annate ’ s characters are very complicated when applicated on the ship. the character of coupling between cells and the environment must be measured to compensate in the radar signal process step. the ship - based over - the - horizon radar uses cfa ( crossed field antenna ) as array antennas ’ cell
艦載超視距雷達使用高頻信號作為發射頻率，其波長較長，在艦船有限的空間內，陣列天線的陣元之間的耦合與陣元與背景之間耦合都十分嚴重，必須測量陣列天線通道的幅相一致性，作為雷達信號處理的補償參數。 -
More information of objects can be obtained from developing the wide - band radar and ultra wide - band radar. with the frequency increasing and the wavelength decreasing, the original objects become electrically large objects. so it is important to study the wide - band electromagnetic scattering characteristics of electrically large objects
發展寬帶雷達和超寬帶雷達可以獲得目標更多、更豐富的信息，而隨著雷達頻率的提高，工作波長的縮小，被研究的雷達目標成為電大尺寸目標，所以研究電大目標寬帶電磁散射特性具有十分重要的意義。
