LOCATING THE BURIED OBJECT IN THE NON-DESTRUCTIVE STRUCTURES USING TH-BPSK UWB SYSTEM

Abstract

The ultra-wideband (UWB) communication system utilizing impulse signals is an attractive technique which can achieve low power consumption, high data rate, and high accuracy in location estimation. One of the applications of UWB is ground penetrating radar (GPR) which has been using to investigate non-destructive structures. In this paper, we proposed a method of locating a buried object in non-destructive structures (concrete, dry soil) using time hopping BPSK UWB (TH-BPSK UWB) modulation system with a certain pulse shape combined with Gauss-Newton nonlinear estimation algorithm. The results of the proposed method were evaluated using computer simulation in terms of the errors of estimated position and spatial resolution.
