摘要 本論文為建立在C波段之地面雷達系統之資料處理。其發射信號為同調步階連續波。系統架構為則由一個微波信號合成器與同調接收器。內容包含信號處理的方法。以及儀表控制使用LabVIEW軟體，透過筆記電腦以控制發射系統與接收系統的同步性，並同時做資料存取的動作。而本研究最終的目的就是透過觀測雷達信號回波與發射波的比較，進而獲得目標物的距離資料。所使用的處理方式在頻率域上面處理，即合成距離資料會在論文中做詳細介紹。 對於系統距離解析度等的分析，本論文利用Matlab並做了相關的模擬。最後在實驗部份，使用角反射器當做目標物測試偵測目標物距離的準確性。 Abstract This thesis is to set up and deal with the materials of a ground based radar system of C band. It transmits the signal as a coherence continuous-wave step frequency . The system constructed by a microwave signal synthesizer and a coherence receiver . Method that the content includes the signal processing method. And instrument use LabVIEW software to control the transmitter and receiver synchronously through a notebook . And this final purpose of research is through observing the radar signal return waves echo compared with the transmitting wave, and then obtained the distance materials of the target . The processing methods deal with those information on frequency domain , that is called “ synthetic range profile “and will detail in the following subject. Analysing of the ability of range resolution of the system have been simulated by Matlab . Finally in order to check the accuracy of detecting the target range direction position ,we use the corner reflector.
