    • 本論文使用Xilinx公司研發的射頻系統單晶片(RFSoC)開發板ZCU111，整合環形天線和射頻收發器來取代網路分析儀作為訊號產生器，在辦公室以及室內走廊進行寬頻通道量測，透過比較各個延遲功率剖面圖來估算收發端的距離，最後利用環形天線能夠產生不同掃描角度功能來偵測訊號的來向，利用上述兩種量測方法來驗證此FPGA開發板能夠實現FMCW寬頻通道響應器。

    This article uses the radio frequency system-on-a-chip (RFSoC) development board ZCU111 developed by Xilinx, which integrate loop antenna and RF transceiver to replace network analyzer as signal generator. This article carries out broadband channel measurements in offices and indoor corridors, and estimates the distance between the receiving and sending ends by comparing the delay power profiles. Finally, we use the loop antenna to generate different scanning angles to detect the direction of the signal, and the above two measurement methods are used to verify that this FPGA development board can realize the FMCW broadband channel sounder.
