Description

Technical Field

[0001] The utility model relates to the technical field of radar detection, in particular to a scanning detection device based on a multi-line radar. Background Art

[0002] Radar detection technology is essentially a high-frequency electromagnetic wave emission and reception technology. Radar waves are generated by self-excitation, and radio frequency electromagnetic waves are directly emitted to the road surface and subgrade. The sampling signal of the road surface and subgrade is obtained by wave reflection and reception, and the detection result is obtained through hardware, software and graphic display system. The sampling frequency used by radar is generally several megahertz (MHz), and the radio frequency frequency of emission and reception may reach above GHz. For example, a laser radar for detecting ships with application number CN202021886761.9 belongs to the field of ship detection technology, and particularly relates to a laser radar for detecting ships. The utility model includes a shell and a laser located on the top of the shell. The laser radar device has a rotating mechanism and a control driver disposed inside the housing. The rotating mechanism is connected to the laser radar device by transmission, and the rotating mechanism drives the laser radar device to rotate. The control driver is electrically connected to the laser radar device through a signal wire. The signal wire passes through an electrical connector. The first end of the electrical connector is rotatably connected to the top of the laser radar device through an electric slip ring. The second end of the electrical connector is fixedly connected to the housing.
