Description

Technical Field

[0001] The present application relates to the technical field of radar antennas, and more specifically, to a radar antenna structure. Background Art

[0002] Radar is a device used to radiate and receive electromagnetic waves and determine its detection direction. When transmitting, the radar must concentrate the energy to radiate in the direction that needs to be illuminated; when receiving, it tries to receive only the echo in the detection direction, and at the same time distinguish the azimuth and elevation of the target, or one of the two. Radar measures three coordinates of the target position (azimuth, elevation and distance). The measurement of two coordinates (azimuth and elevation) is directly related to the performance of the antenna. Therefore, antenna performance is more important for radar equipment than for other electronic equipment.

[0003] According to the search, the Chinese patent with publication number CN218770039U discloses a radar antenna structure that is easy to fold, which includes a base, a support column is installed at the middle position of the upper end surface of the base, a vertical plate is installed on the upper end surface of the support column, a U-shaped seat is installed on the front end surface of the vertical plate, vertical shafts are arranged on both sides of the front end surface of the U-shaped seat, a gear is sleeved on the upper part of the outer surface of the vertical shaft, a connecting plate is sleeved on the lower part of the outer surface of the vertical shaft, an antenna array surface is fixedly connected to the opposite side of the outer surface of the two connecting plates, a connecting shaft is arranged on one side of the lower end surface of the U-shaped seat, a turntable is sleeved on the lower part of the outer surface of the connecting shaft, a number of slots are evenly arranged on the outer surface of the turntable, a support plate is arranged on the front and rear of the other side of the lower end surface of the U-shaped seat, and a pin is arranged on the opposite side of the outer surfaces of the two support plates. This application can reduce the lateral size of the two antenna array surfaces, save space, facilitate transportation, and save costs.

[0004] Regarding the above-mentioned related technologies, the applicant believes that the setting of the handle requires the staff to manually operate when it is necessary to control the two antenna arrays to be folded, which is very inconvenient. Therefore, we propose a radar antenna structure. Utility Model Content
