Multi-channel Ground Penetrating Radar based on ultra-wideband short-pulse signal: Hardware and software

摘要

In [1, 2] recent state of our multi-channel Ground Penetrating Radar (GPR) design is reflected. In this paper we compare that former design with the new one which is free of some drawbacks. Both GPRs are suitable for diagnostics of road coatings, detection and recovery of subsurface infrastructure (pipes, cabling). GPRs include TX/RX module, antenna switch, multi-element antenna, carrier vehicle and control/processing computer with dedicated software. This software allows GUI, controls TX/RX module, accepts the data from TX/RX module, builds 3D radio image of subsurface volume. As well, dedicated software enables to estimate the geometry and electrophysical parameters of subsurface volume and objects inside of it. For this, so-called Computational diagnostics method is implemented which is based on reverse problem solution. Experimental results are presented.
