[0002] Radar is an electronic device that uses electromagnetic waves to detect targets. Radar emits electromagnetic waves to illuminate the target and receives its echo, thereby obtaining information such as the distance from the target to the electromagnetic wave emission point, the rate of change of distance (radial velocity), azimuth, and altitude. Radar has shown great application potential in flood monitoring, sea ice monitoring, soil moisture surveys, forest resource inventory, and geological surveys. In order to ensure the construction quality and safety of tunnels, radars need to be used for all-round detection during the actual tunnel inspection process. Generally, the radar will be fixed on a bracket, and relevant personnel should pay close attention to the images and related data sent back by the geological radar and collect them.
