本論文提出兩組基於自我注入鎖定原理之微小化非接觸式感測雷達系統，從振盪器與不等功率分枝耦合器的設計概念入手，設計SIL振盪器的鎖定範圍、輸出功率、與推導不等功率分枝耦合器的矩陣分析。在論文中段將雷達收發機整合在ADS模擬環境中，透過模擬軟體得知自我注入鎖定雷達收發機的工作狀況，得出模擬與實作有相同的趨勢，最後進行雷達架構的整合，並從頻譜與示波器分析兩雷達模組的效能得出，雷達模組I有較佳的振幅表現，而雷達模組II有較佳的訊號雜訊比表現。

This thesis proposes two miniaturized Printed-Circuit-Board(PCB) non-contact radar systems based on Self-Injection-Locked(SIL) principles. According to the design concepts of the oscillator and unequal power branch-line coupler. Design the locking range and power of Self-Injection-Locked Oscillator(SIL Oscillator) and derives the matrix analysis of the unequal power branch-line coupler. In the middle of the papper, the radar transceivers will be integrated into the Advanced Design System (ADS) simulation environment, and the working state of the SIL radar transceivers will be interpreted through a simulated software in order to obtain the same trend in the simulated and implement test environment. Integrated the radar architecture at the end. Showing the ability of this two sets of radar from triangle experiment . The measurement results demonstrate that the first set of radars perform better amplitude , while the second set of radars perform better sensitivity.
