臺灣博碩士論文加值系統

本論文主要利用頻率調變連續波(FMCW)雷達來達成短距離測距的應用，並以該雷達收發模組的規格作為系統設計考量。本論文主要分為三個部分來分別做討論。
第一部分敘述FMCW的基本概念，以及說明簡要的系統分析，接者再針對測距應用的靜動態分析，之後對極端的兩種情形做分析。第二部分將介紹FMCW雷達系統的系統行為模擬，其操作頻率為24 GHz至 24.25GHz，內容包括系統應用方面的測距模擬以及系統層級行為模擬。最後一部分則是驗證該雷達收發模組的實用性，可以了解該頻率的電磁波對不同材質物體反射情形以及該系統量測的精確度，最後量測結果再與模擬結果互相比較。

In this thesis, utilizing the frequency modulation continuous wave(FMCW) radar to achieve short-range measurement application and the radar transceiver module's specifications for system design considerations is proposed. This thesis is divided into three parts to be discussed separately.
The first part describes the basic concepts of FMCW, including analysis of brief system, static and dynamic analysis of range applications, and analysis of extreme cases. The second part introduce the system behavior simulation of FMCW radar system, which operates in the frequency range of 24GHz to 24.25GHz. The content includes system simulation and system-level behavior simulation. The last part is to verify practicality of the radar transceiver module to understand the frequency of electromagnetic waves on different material objects. We give the accuracy of the measurement system and the measurement results compared with simulation results.
