Some advances in UWB GPR

Abstract

A principle of operation and arrangement of UWB antenna systems with frequency independent electromagnetic decoupling is discussed. The peculiar design of the antenna makes it possible to use it in two different modes: horizontal scanning mode and accurate definition of local object location mode. The technique for automatic local objects detection on GPR images is considered. It is based on the Hough transform for detection of hyperbolic curves. Estimation of the accuracy of the objects' measured coordinates and evaluation of the detection probability have been performed for the case of automatic interpretation of GPR sounding results. © 2009 Springer Netherlands.
