Experimental Analysis of Range Detection for Portable SFCW Ground Penetrating Radar

This paper discusses the experimental analysis of range detection for a portable stepped-frequency continuous-wave (SFCW) ground penetrating radar (GPR) in measuring some objects. The SFCW-GPR was designed in portable and realized modularly using some RF components. The measurements are made with an object buried beneath the sand surface with a depth of 0.2m, 0.4m, and 0.6m. As the measurement are performed above the sand, hence there are two reflected waves obtained, that are from the surface of sand and from the buried object. The reflected waves known as time delay of the object are then analyzed to determine the range detection. The measurement of buried objects at the deep of 0.2m, 0.4m, and 0.6m provides the range detection of 0.204m, 0.400m, and 0.601m, respectively, showing the adequate accurateness of realized SFCW-GPR.
