關鍵詞：ZedBoard，AD9361，ADS-B，PYNQ。 本研究聚焦於 ADS-B（Automatic Dependent Surveillance-Broadcast）技術，這是一 項用於航空領域的飛機定位和通訊技術。ADS-B 是利用衛星定位系統（如 GNSS）來確 定飛機的精確位置，並將這些位置數據以廣播方式傳送給地面站和附近的其他飛機。其 目的在於提升空中交通的安全性、效率和準確性。 我們的研究利用了 ZedBoard 開發板（基於 Xilinx Zynq®-7000）以及 AD9361 RF Agile Transceiver 平台，實現了軟硬體的應用。通過 PYNQ 控制 ZedBoard 和 AD9361， 我們成功實現了 ADS-B 訊號的發射。 研究的重點放在 ADS-B 訊號擬真器的設計和實現。首先，在 ZedBoard 上建立了 PYNQ 環境，並在 Linux 下使用 Jupyter 建立了使用者介面(UI)。接著，我們設計了硬體 層，將軟體和硬體結合在一起。並且，利用市面上的 ADS-B 接收器（RTL2832U+R820T2） 進行驗證。 這項研究為 ADS-B 訊號擬真器的設計和實現，透過 ADS-B 訊號擬真器的應用，我 們得以有效模擬飛機的飛行軌跡。利用 ADS-B 訊號擬真器，我們能進行接收機靈敏度 等相關測試，同時亦能模擬多架飛機的測試情境，以驗證接收機的性能與能力。;Keywords: ZedBoard, AD9361, ADS-B, PYNQ. This research focuses on ADS-B (Automatic Dependent Surveillance-Broadcast) technology, which is an aircraft positioning and communication technology used in the aviation field. ADS-B uses satellite positioning systems (such as GNSS) to determine the precise position of an aircraft and transmits the position data to ground stations and other nearby aircrafts though the way of broadcast. The purpose is to improve the safety, efficiency and accuracy of air traffic. Our research utilized the ZedBoard development board (based on Xilinx Zynq®-7000) and the AD9361 RF Agile Transceiver platform to achieve close collaboration between software and hardware. By controlling ZedBoard and AD9361 through PYNQ, we have successfully achieved the emission of ADS-B signal. The focus of the research is on the design and implementation of the ADS-B signal simulator. First, a PYNQ environment was established on a ZedBoard, and an intuitive user interface was established using Jupyter under Linux. Next, we designed the hardware, combining software and hardware. Finally, we successfully implemented the ADS-B transmitter and verified it using the ADS-B receiving platform (RTL2832U+R820T2) on the market. This research is the design and implementation of the ADS-B signal simulator. Through the application of the ADS-B signal simulator, we can effectively simulate the flight path of the aircraft. Using the ADS-B signal simulator, we can not only conduct receiver sensitivity and other related tests, but also simulate the test situation of multiple aircraft in order to verify the performance and capabilities of the receiver.
