本論文主要係採用都卜勒雷達原理實現5.8 GHz非接觸式手勢感測雷達模組，並整合和差陣列天線研製一型單脈衝雷達模組系統，用以辨識散射物方向，其雷達模組設計、實現方式及量測模擬結果皆於本論文中詳細討論。在非接觸式手勢感測雷達模組中，本論文首先採用複合式左/右手合成傳輸線之洩漏波天線來實現手勢訊號感測雷達模組之掃描功能。由實驗結果可驗證，當手勢於波束掃瞄範圍內揮動時，此雷達感測系統不僅可偵測5種手勢，分別為「手勢往前」、「手勢往後」、「手勢來回」、「垂直手勢」與「水平手勢」，並可進一步計算手勢移動距離。而在單脈衝雷達系統模組中，本論文採用一和差陣列接收天線將接收之散射物反射訊號分成和(Σ)訊號與差(Δ)訊號，並使用和差訊號之比值求得散射物反射波之入射角度。由實驗結果可知，當散射物置於偏離天線中心「7°」位置上，其計算之相對角度為10.3°與實際角度誤差為3.3°，而計算之距離量測誤差為2.5 %。

This thesis presents a 5.8 GHz non-contact Doppler radar module for the gesture sensing application. Furthermore, the radar module combines with a sum/difference antenna array to form a monopulse radar module for the azimuth angle detection of the scattering object. In order to achieve the capability of space scanning, the composite right/left-handed transmission line is adopted to develop a leaky-wave antenna, and then employed in the developed radar module. According to the experimental results, the radar system can not only detect five different gestures, but also calculate the distance of moving gesture. Moreover, for the monopulse radar, the sum/difference antenna array is used to receive the reflected wave from the scattering object, and these two sets of signals are used to calculate the azimuth angle of the scattering object. When the scattering object is located along the direction of "7 °" with respect to the center of the antenna array, the calculated angle from relative angle of the calculated actual angle of 10.3 ° with an error of 3.3 °, namely a relative error of 2.5 % .
