Problems solved by technology
The 360° panoramic camera can realize close to 360° surround view monitoring, but the viewing distance is only about 20 meters
Compared with camera monitoring, millimeter-wave radar has a working distance of up to 200 meters and will not be affected by weather conditions. However, the field of view of millimeter-wave radar is generally between 90°-140°, and the monitoring is not in place

The invention belongs to the technical field of radars, and discloses a radar monitoring device which comprises a plurality of radar assemblies which are sequentially connected end to end, each radar assembly comprises an antenna plate and an antenna arranged on the outer side of the antenna plate, and the antennas are used for emitting electromagnetic waves outwards. Field angles of electromagnetic waves emitted by any two adjacent radar assemblies are set as a first field angle and a second field angle, and adjacent boundary lines of the first field angle and the second field angle coincide or detection areas covered by the first field angle and the second field angle partially coincide. The multiple radar assemblies are sequentially connected end to end to form an annular body structure. The adjacent boundary lines of the field angles of electromagnetic waves emitted by any two adjacent radar assemblies coincide or the detection areas covered by the two field angles coincide partially, so that the detection areas of the multiple radar assemblies are overlapped in sequence, and the whole circumferential area of the annular body structure formed by the multiple radar assemblies can be detected. Therefore, the whole circumferential monitoring of the radar monitoring device is realized, and the monitoring is more reliable.
Description
technical field [0001] The invention relates to the technical field of radar, in particular to a radar monitoring device. Background technique [0002] The monitoring system is one of the most widely used systems in the security system. The traditional monitoring system generally uses a camera to shoot the monitoring area. Cameras are divided into 360° panoramic cameras and non-360° panoramic cameras. The viewing distance of the non-360° panoramic camera is about 100 meters, and the field of view is about 20°. The 360° panoramic camera can realize close to 360° surround view monitoring, but the viewing distance is only about 20 meters. The shooting quality of the camera will also be affected by weather conditions (such as day, night, sand, smog, or rain and snow). [0003] Based on the above-mentioned defects in camera monitoring, millimeter-wave radar emerged as a new monitoring device. The millimeter-wave radar emits electromagnetic waves through its antenna to detect ...
