论文摘要
跨频率地面穿透雷达（GPR）系统用于检测埋在高介电常数土壤下的物体。使用混合接收器的不同中间频率带宽（IFBW），并比较测量结果。结果表明，IFBW可能会影响系统的信噪比（SNR）。实验结果表明，当使用适当的IFBW时，可以清楚地检测到不同材料的对象。
A stepped frequency ground penetrating radar (GPR) system is used for detecting objects buried under high permittivity soil. Different intermediate frequency bandwidth (IFBW) of the mixing receiver is used and measurement results are compared. It is shown that the IFBW can affect the system's signal-to-noise ratio (SNR). Experimental results show that objects of different materials can clearly be detected when the appropriate IFBW is used.
