Description of the development:
()
GPR is a video-pulse radar system, which is used for sensing subsurface structures of the video-electromagnetic signal. Working band signal of 0.8 to 1.6 GHz, which can determine the location of objects within a few millimeters to tens of centimeters, depending on the depth and the electrical characteristics of the medium under the surface. Sensing objects can be any dielectric layers, and metal dielectric structures are in dielectric layers, as well as cracks and cavities in these layers. GPR consists of: - Multi-channel transceiver (hardware unit); - UWB transceiver antenna system with a high level of isolation between the transmitting and receiving modules; - Software package management transceiver and antenna system antennas, as well as programs for processing radar data and visualize the results of sensing subsurface structures.
