Description

Technical Field

[0001] The utility model relates to the technical field of radar measurement, in particular to a vehicle-mounted radar measurement device. Background Art

[0002] Radar antennas are usually installed at a higher position (higher than the surrounding trees), and the radar antenna emission angle is generally greater than 5 degrees. In order to avoid blocking the radar signal, there are rarely tall buildings around the radar station. This also makes it extremely difficult to measure and capture radar transmission signals. According to the parameter requirements of existing radar test equipment, the detection of radar field signals (signals emitted by the radar or signals reflected by the equipment aircraft) needs to be between 0.5 kilometers and 40 kilometers away from the radar station, without obstruction or reflection.

[0003] After searching the publication (announcement) number: CN108303681A, a vehicle-mounted radar measuring device and a radar test system are disclosed. The vehicle-mounted radar measuring device provided by the invention includes a radar test module, a communication module, a collaborative office module and a main control module; the radar test module is used to movably and height-adjustably receive the electromagnetic wave signal emitted by the radar in the radar station; wherein, since the radar test module can movably and height-adjustably receive the electromagnetic wave signal emitted by the radar in the radar station, the purpose of the radar test module being close to the height of the radar station can be achieved, so there is no need to find a test location that is close to or higher than the radar station in height. The selection range of the test location is larger, which can solve the problem of difficulty in selecting the test location in the prior art, so it is more convenient to select the test point, and the work of the radar test antenna aiming at the radar station can be accurately completed.

[0004] Although the above scheme realizes the lifting and lowering of the radar test antenna by lifting the mast, thereby making the radar test site more convenient, it can only realize the measurement of the radar test antenna in the vertical direction and cannot realize the angle adjustment of the radar. For this reason, we propose a vehicle-mounted radar measurement device. Utility Model Content

[0005] The main purpose of the utility model is to provide a vehicle-mounted radar measuring device, which solves the problem that the radar test can only be measured in the vertical direction but the angle adjustment of the radar antenna cannot be achieved by setting an angle adjustment unit and a height adjustment unit.

[0006] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0007] A vehicle-mounted radar measuring device comprises a main body unit, an angle adjustment unit arranged above the main body unit, a height adjustment unit arranged inside the angle adjustment unit, and a horizontal adjustment unit arranged on the side of the height adjustment unit;

[0015] Preferably, the horizontal adjustment unit further comprises a limiting washer installed on the inner side wall of the transverse seat, and the limiting washer is sleeved on the peripheral side surface of the screw rod.

[0016] Compared with the prior art, the utility model has the following beneficial effects:

[0017] In the utility model, by setting up an angle adjustment unit and a height adjustment unit, when it is necessary to measure the height of the radar, the first drive motor drives the threaded shaft to rotate, and at this time the transverse member can drive the radar member to move up and down along the threaded shaft, thereby realizing the height adjustment of the radar member, and when the second drive motor drives the lead screw to rotate, the radar member can move left and right along the lead screw, so that the received signal can be collected more accurately; when it is necessary to adjust the angle of the radar, the telescopic end of the electric telescopic rod is extended and retracted, and the transmission plate moves the second connecting seat left and right, and the transmission is that the first connecting seat drives the lifting seat to rotate around the U-shaped seat, thereby realizing the angle adjustment of the radar member.
