雷達，是“radio detection and ranging”的縮寫及音譯。將電磁能量以定向方式發射至空間之中，藉由目標物對電磁波的散射或反射波，可以計算出該物體方向、高度、速度，甚至物體的形狀。
近年來隨著物聯網(IOT)應用範圍不斷擴大，許多物聯網應用依靠嵌入式傳感器執行關鍵測量任務，或作為控制電路的重要組成部分。物聯網的概念以無線傳感網絡為基礎，新型傳感器的開發可實現新的應用。而現今雷達傳感器已成為物聯網和嵌入式設計中的重要設計單元。雷達網絡可以是無線傳感器的重要分支，用於檢測環境中物體的位置、速度和軌跡。雷達通過任何項目的連接，智能地識別後，能定位、跟踪、監控、管理、信息交換和通信。
一個雷達網絡包含多個雷達節點以重疊區域的覆蓋範圍。它分兩個階段運作，信息收集和信息檢索。本地雷達從環境中收集數據，然後將數據傳遞到外部世界進行數據處理。因此，每個雷達節點必須具有傳感和通信能力。
本論文提出了一個無線感測通訊單元。在無線感測中，此單元能做為FMCW雷達使用，偵測目標物距離。在無線通訊中，此單元則能支持BASK，BPSK和BFSK等調變互相通訊，彼此聯繫形成網路。而本論文所提出並之應用於短程雷達網絡的射頻單端口混頻器優先級雙工收發器，發射端與接收端能同時收發，並以單一天線進行電磁波的發射與接收。主要組成電路有射頻前端電路、單端轉雙端電路、可變增益放大器、抗混疊濾波器、類比數位轉換器與鎖相迴路。本論文提出之收發器面積消耗為2.85mm2，消耗功率為190mW，操作頻率範圍為3.1GHz~3.6GHz。內文開頭會先介紹雷達網路並依雷達天線種類加以比較，接著依序講解數學模型、設計流程，提出電路架構之模擬結果、量測考量，最後對於電路提出結論與展望。

Radar, is the abbreviation and transliteration of “radio detection and ranging”. Electromagnetic energy is emitted into the space in a direction, so the position, height and velocity of the object, and even the shape of the object, can be calculated by electromagnetic waves scattered or reflected from the object.
In recent years, Internet of Things (IoT) has expanding. Embedded sensors are not only being viewed as important control circuit parts but also being used by many IoT in crucial measurements.
The concept of the Internet of Things is based on wireless sensor networks, and the development of new sensors has made new applications possible. Nowadays, radar sensors have become an important design unit for IoT and embedded design. Radar networks is an important branch of wireless sensors to detect the location, velocity and trajectory of objects in the environment. Through the connection of any item, radar exchanges information to achieve intelligent identification, and then locate, track, monitor and manage signal.
A radar network contains multiple radar nodes to overlap area coverage. The network operates in two phases, information gathering and information retrieval. A local radar collects data from the environment and then passes the data to the outside world for data processing. Therefore, each radar node must have the capacity of sensing and communication.
This dissertation proposes a wireless sensing communication unit. In wireless sensing, this unit can be used as a FMCW radar to detect target distance. In wireless communication, this unit can support BASK, BPSK and BFSK to communicate and connect with each other to form a network. The RF single-port mixer-first duplex transceiver proposed in this dissertation is applied on short-range radar networks. The transmitter and receiver can transmit and receive simultaneously, and electromagnetic waves are transmitted and received by a single antenna. The main circuit components are RF front-end circuits, single-ended to double-ended circuits, variable gain amplifiers, anti-aliasing filters, analog-to-digital converters and phase-locked loops. The transceiver area consumption proposed in this paper is 2.85mm2, the power consumption is 190mW, and the operating frequency range is 3.1GHz~3.6GHz. The dissertation begins with an introduction to the radar network and compares radar antenna types. Next, I will explain the mathematical model, the design flow, the simulation results of the circuit architecture, the measurement considerations. At last, I will make a conclusion and further work on circuit.
