Description

Technical Field

[0001] This utility model belongs to the field of radar testing technology, specifically relating to a testing device for millimeter-wave radar. Background Technology

[0002] Millimeter-wave radar is widely used in military and civilian fields due to its high resolution and anti-jamming capabilities. However, testing and calibrating millimeter-wave radar presents a technical challenge, particularly in testing its angular measurement accuracy. Corner reflectors, due to their ability to reflect radar signals, are widely used in testing radar systems.

[0003] Many existing testing devices do not have shielding structures, making the radar susceptible to interference during testing, which in turn affects the test results.

[0004] Therefore, further improvements will be made to address the aforementioned issues. Utility Model Content

[0005] The main purpose of this invention is to provide a testing device for millimeter-wave radar, which is linked by a shielding box, a radar mounting module, and a corner reflector mounting module, so that the radar test is located in the shielding box, isolating external interference and improving the detection accuracy.

[0006] To achieve the above objectives, this utility model provides a testing device for millimeter-wave radar, comprising a shielded box, a radar mounting module, and a corner reflector mounting module, wherein the radar mounting module and the corner reflector mounting module are respectively mounted at both ends of the shielded box, wherein:

[0008] The radar mounting module includes a radar mounting plate and a limiting unit. The radar mounting plate is fixedly connected to the first bending part, the third bending part, the fifth bending part, and the seventh bending part, respectively. The radar mounting plate is provided with a placement hole for placing the radar to be tested. The limiting unit is fixedly installed on the outside of the radar mounting plate and is provided with a first limiting block, a second limiting block, a third limiting block, and a fourth limiting block surrounding the placement hole.

The reflector mounting plate is fixedly connected to the second bend, the fourth bend, the sixth bend, and the eighth bend, respectively. The mounting unit includes a mounting bracket and a fixing block. The mounting bracket is fixedly mounted on the inner side of the reflector mounting plate and is provided with a sliding groove. The fixing block is mounted in the sliding groove (the position of the fixing block in the sliding groove can be adjusted according to test requirements) and is used to mount the corner reflector.

[0010] As a further preferred technical solution to the above technical solution, the radar mounting module also includes a clamp, which is located on one side of the limiting unit (used to press and fix the radar to be tested, thereby improving structural stability).

[0011] As a further preferred technical solution to the above technical solution, the outer side of the reflector mounting plate is provided with several casters (for easy handling and transportation).
