Effects of Intermediate Frequency Bandwidth on Stepped Frequency Ground Penetrating Radar

Wenhao Luo, Hai-Han Sun, Yee Hui Lee, Abdulkadir C. Yucel, Genevieve Ow, Mohamed Lokman Mohd Yusof

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.
