GPR depth measurement by spectrum analysis

In technology of GPR, measuring the depth of the target underground is one of the important aspects. In routine measurement, measure error for measure height is greatly affected by aviation stability. Especially when measuring the depth of underground targets, because of the change of spread route during the electromagnetic wave penetrating ground, the route between target and radar cannot be directly measured. In this paper, spectrum analysis based method for measure of route is investigated which can be used to accurately measure the route between underground target and radar. In ground penetrating radar applications, it is propitious to improve the measure precision and remove the effect of aviation on measuring height.
