    Abstract: 目前國內透地雷達檢測等相關研究,如結構物、大地、橋梁、古蹟…等檢測十分普遍,但對於透地雷達檢測混凝土結構內、外部,因天侯狀況與水氣的變化,所量測之電磁波反射訊號特徵參數部分則較少去探討。而非破壞檢測技術的優缺點,須根據檢測對象特性與應用在不同環境條件下,檢測不同結構物內部訊息。因此,本研究以透地雷達電磁波入射到不同電性之介質或物體即產生全反射或部分反射之物理現象,經過接收後進行訊號判讀與影像處理分析後,探討混凝土結構構件在乾、濕狀態下之相對介電常數之改變量。而本研究採用1GHz高頻天線量測混凝土構件在不同
    The ground penetrating radar ( GPR ) techniques have been widely used in civil and geotechnical engineering. Due to the complex boundary of concrete and environment conditions, the scanning-image of cross-sectional profile identification of GPR depends on
