Embodiment 1
[0046] The present invention provides a radar range measurement system. In this embodiment, a millimeter-wave radar is used as an example for illustration. In other embodiments, it can also be used to measure the range of other radars, which is not limited here.
[0047] refer tofigure 1 As shown, the system includes: a radar 1 , a radar probe 2 , a bracket, a first rotary drive 3 , a second rotary drive 4 , a first angle sensor 5 , a second angle sensor 6 and a main controller.
[0048] The radar 1 has a emitting surface, and the emitting surface has a center point, and a line perpendicular to the emitting surface and passing through the center point is defined as the central axis of the radar.
[0049] The radar probe 2 is used to detect the signal strength of the radar 1 in real time. The radar probe 2 has a cone-shaped detection area, and the central axis defining the cone-shaped detection area is the central axis of the probe.
[0050] Both the first rotary driving member...
Embodiment 2
[0065] Based on the radar range measurement system of Embodiment 1, the embodiment of the present invention also provides a radar range measurement method, including the following steps:
[0066] S1: Adjust the positions of the radar probe 2 and the second rotary driving member 4 on the support so that the separation distance between the radar probe 2 and the emitting surface of the radar 1 satisfies the separation distance range.
[0067] Described separation distance range those skilled in the art can set according to experience and experimental data, need meet under the separation distance outside the separation distance range, radar probe 2 can't detect the data of radar 1, therefore, under this separation distance Radar 1 data is meaningless, and there is no need to recordRadar 1 data at this separation distance.
[0068] S2: The main controller collects radar wave intensity data in real time through the radar probe 2.
[0069] S3: The main controller controls the first...

Abstract
The invention relates to a radar range measurement system and method. The system includes: a radar, a radar probe, a bracket, a first rotary drive, a second rotary drive, a first angle sensor, a second angle sensor and a main controller; the main control The detector calculates the detection range parameters of the radar according to the collected rotation angles of the first rotating drive member and the second rotating drive member, the intensity of radar waves detected by the radar probe, and the distance between the radar probe and the radar emitting surface. The invention has the beneficial effects of high degree of automation, simple and convenient operation, high reliability and high efficiency.
Description
technical field [0001] The invention relates to the technical field of radar detection, in particular to a radar range measurement system and method. Background technique [0002] At present, the requirements of national standards and regulations for driving safety are increasing day by day. At the same time, vehicle manufacturers and vehicle occupants pay more attention to driving safety. The ratio of automatic emergency braking system and blind spot monitoring and alarm system is getting higher and higher. As the core detection sensor of most automatic emergency braking systems and blind spot monitoring and alarm systems, millimeterwave radar has the characteristics of high detection accuracy and large detection distance, so it is widely used. [0003] The directivity of the millimeter wave, that is, the millimeter wave intensity level of the millimeter wave radar at each angle in its detection area, directly determines the horizontal and vertical measurement range of the...
