Description

Technical Field

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

[0002] Radar is an electronic device that uses electromagnetic waves to detect targets. It transmits electromagnetic waves and receives their echoes to obtain information such as the target's distance, speed, direction, and altitude. After radar production and development are completed, testing its actual effectiveness becomes a critical step.

[0003] The radar test device can be used to simulate the movement of the target object. The electromagnetic waves sent by the car radar are reflected by the target object to form an echo signal, thereby realizing the comprehensive performance test of the radar system. However, the target object in the current radar test device moves on a track of fixed length, and can only be tested for a fixed movement distance, which is inconvenient to use. In the prior art, for example, the invention patent with application number 202010258154.6 provides a radar test device, which solves the problem that only fixed movement distances can be tested in the prior art by modularizing the bracket. However, when it is necessary to extend the maximum movable distance of the motion test module, it is necessary to splice the modules on the basis of the original bracket. This method not only requires the pre-setting of many modules, but also the splicing is time-consuming and labor-intensive. Utility Model Content

[0023] By providing a workbench that can be raised and lowered in the vertical direction for placing the radar to be tested, a Doppler instrument 12 arranged on the base 1 or at a certain height above the base 1, and a longitudinal ruler 6, different test distances can be flexibly adjusted. At the same time, the height adjustment of the workbench does not require manual judgment through the setting of the induction switch 7, thereby improving the accuracy of the test distance.

[0024] Specifically, if Figure 1As shown, in this embodiment, the base 1 is provided with a first workbench 2, a second workbench 3 and a third workbench 4 in order from top to bottom; the first workbench 2 can be automatically raised and lowered by remote control via an automatic lifting rod 8; the second workbench 3 can be manually raised and lowered via a manual lifting rod 9; and the third workbench 4 can be manually raised and lowered via a manual lifting assembly 10. A support platform 5 is provided at a fixed height between the second workbench 3 and the third workbench 4 for placing the Doppler instrument 12. The Doppler instrument 12 can simulate a moving object at a fixed position, providing a detectable target for the radar system, and can perform effective testing and calibration even in the absence of an actual moving object. In this embodiment, the longitudinal ruler 6 is a foldable ruler, which can be folded and stored when not in use to reduce space occupancy.

[0025] In this embodiment, the induction switch 7 is a photoelectric switch, and the power controller 11 for automatically raising and lowering the first workbench 2 is electrically connected to the induction switch 7; when the first workbench 2 is lifted to the position corresponding to the induction switch 7, the induction switch 7 detects the first workbench 2, and it sends an electrical signal to turn off the power controller 11 to stop the first workbench 2 from lifting; so as to accurately control the lifting height of the first workbench 2.

[0026] Of course, in other embodiments, a prompting device electrically connected to the induction switch 7 may also be included. When the first workbench 2, the second workbench 3, and the third workbench 4 are raised to a specific test distance, the induction switch 7 detects the workbench and sends an electrical signal to trigger the prompting device to remind the tester that the workbench has been raised to the test position. The prompting device may be a warning light or an alarm. The first workbench 2 may also be remotely raised or lowered by a remote trigger switch.

[0027] In this embodiment, the base is provided with universal wheels and a support rod connected to the base, so that the radar test device can be moved and tested at any position, which saves space and does not take up much space.
