本論文提出基於自我注入鎖定(Self-Injection Locking﹐SIL)技術的合成孔徑雷達(Synthetic Aperture Rader﹐SAR)，在實驗上將SIL雷達收發天線放置於等速的移動式平台，來達成SAR量測的效果。 應用SAR成像演算法獲得的二維成像資訊之後，可以將目標標記出確切的座標。再透過結合SIL技術之調頻連續波(Frequency Modulated Continuous Wave﹐FMCW)雷達慢時間(slow-time)的相位檢測來提取目標的都卜勒信息。本論文對室內環境中的單及多物體定位與振動頻率偵測以及單及多人體的定位與生理感測分別進行了實驗。 結果表明，所提出的方法不僅可以準確地確定SAR成像中目標的位置，還能可靠地獲得目標的都卜勒信息。

This study presents a synthetic aperture radar (SAR) based on self-injection locking(SIL) technology. In the experiment, the transmit (Tx) and receive (Rx) antennas of a SIL radar were mounted on a constant-speed moving platform to achieve SAR measurements. 2-D imaging of targets was then constructed by the SAR imaging algorithm to mark up the correct coordinates of the targets. Moreover, the Doppler information of the targets was further extracted from the detected slow-time phase using a combined SIL and frequency-modulated continuous-wave (FMCW) radar.This study conducts experiments to detect the positions and vibration or vital-sign frequencies of single and multiple targets in an indoor environment. The results prove that the proposed method can not only accurately determine the targets’ positions according to the SAR images but also obtain their Doppler information reliably.
