Abstract:	雷達目前被廣泛應用在軍事、航空、氣象等領域上，並且常利用脈衝壓縮技術提升偵測性能，若成功接收到目標的回波訊號，通過匹配濾波器會形成高於旁瓣的峰值，便可由延遲取樣點數推算目標距離，因此雷達訊號的自相關特性對於系統性能非常重要。格雷互補序列對(Golay Complementary Sequence Pair)的特點在於：兩個序列的自相關函數分別各有旁瓣，但在將兩者的自相關函數相加後，所有旁瓣項會互相抵消，僅保留主峰的位置。本研究將格雷序列應用於雷達系統，並在Xilinx ZCU111 RFSoC平台環境下實現雷達發射機與接收機模組，可以通過調整過取樣率、脈衝重複週期及脈衝數來應對不同的偵測環境。並模擬偵測雷達截面積(Radar Cross Section) 0.1 m^2的目標，在不同距離下的偵測性能，同時也擁有不易受發射端直接耦合訊號(Direct-Path Coupling)干擾之特性。 ;Radar technology is widely used in military, aviation, and meteorological applications, and pulse compression techniques are commonly employed to enhance detection performance. When the radar successfully receives a target’s echo, a matched filter produces a mainlobe peak that exceeds the sidelobes, enabling the estimation of target range from the delay sample index. Therefore, the autocorrelation characteristics of the radar waveform are crucial to overall system performance. A Golay Complementary Sequence Pair features two sequences whose individual autocorrelation functions contain sidelobes; however, when the two autocorrelations are summed, all sidelobe components cancel out, leaving only the main peak. This thesis applies the Golay sequence to a radar system and implemented on the Xilinx ZCU111 RFSoC platform, integrating both radar transmitter and receiver modules. The system allows adjustments of oversampling rate, pulse repetition interval, and pulse number to accommodate different detection scenarios. In addition, the detection performance for targets with a radar cross section (RCS) of 0.1 m² at various ranges is evaluated through simulations. The results demonstrate that the proposed system is capable of reliable target detection while exhibiting strong robustness against direct-path coupling interference from the transmitter.
