Multi-channel ground penetrating radar: Hardware and software

Current state of our multi-channel GPR elaboration is presented. GPR is designed for diagnostics of roads' coating, detection and recovery of subsurface infrastructure in soil down to 1.2 meters depth. Multi-channel architecture allows inspecting 1-m width strip of ground surface simultaneously. Designed GPR parameters, its hardware and software are discussed. 3D images of subsurface objects formed by GPR as well as results of objects geometry restoration are presented. Dedicated software enables estimating the geometry and electro-physical parameters of subsurface volume and objects inside of it. For this, so-called Computational diagnostics method, which is based on reverse problem solution, is implemented.
