Abstract

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.

中频带宽对步进频率探地雷达的影响
采用阶跃频率探地雷达(GPR)探测高介电常数土壤下的目标。采用不同的中频带宽(IFBW)混合接收机，并对测量结果进行了比较。结果表明，IFBW会影响系统的信噪比(SNR)。实验结果表明，使用合适的IFBW可以清晰地检测到不同材料的物体。
