Description

Technical Field

[0001] This invention belongs to the field of radar calibration and testing technology, and particularly relates to a millimeter-wave radar shielding box that uses both angle reflection and target simulator. Background Technology

[0002] During the calibration and testing of millimeter-wave radar, it is usually necessary to calibrate and test the millimeter-wave radar separately using an angle reflector and a target simulator in a shielded box. This means that two shielded boxes are needed to install the angle reflector and the target simulator respectively; the angle reflector shielded box is used for the calibration of the millimeter-wave radar, and the target simulator shielded box is used for the testing of the millimeter-wave radar.

[0003] Conventional millimeter-wave radar calibration and testing require two shielded enclosures to house the angle reflector and the target simulator, respectively. This increases the number of enclosures and the floor space required for the equipment. Therefore, this invention proposes a millimeter-wave radar shielded enclosure that simultaneously utilizes the angle reflector and the target simulator to solve the aforementioned problems. Utility Model Content

[0004] This invention provides a millimeter-wave radar shielding box that simultaneously uses angular reflection and a target simulator, aiming to solve the problems mentioned in the background art.

[0005] This invention is implemented as follows: a millimeter-wave radar shielding box that simultaneously uses angle reflection and target simulator, comprising a right frame and a left frame.

[0006] The right frame and the left frame are combined to form a shielded box;

[0007] The right frame is equipped with a shielding wall, an angle reflector, and a target simulator. The angle reflector is located behind the shielding wall, and the target simulator is located behind the angle reflector. The angle reflector is movable and can be raised and lowered. The angle reflector is equipped with wave-absorbing cotton, which is located on the side close to the target simulator.

[0008] Preferably, the angle-reversing device includes a telescopic support rod, which drives the angle-reversing device to rise and fall.

[0009] Preferably, during millimeter-wave radar angle reflection calibration, the telescopic support rod drives the angle reflection device to rise to the same height as the target simulator device. At this time, the angle reflection device is higher than the height of the shielding wall, and the wave-absorbing cotton blocks the target simulator device to avoid signal interference testing.

[0010] Preferably, during millimeter-wave radar target simulation testing, the telescopic support rod lowers the angle reflector to the shielding wall, which can then block the angle reflector. At this time, the angle reflector will be blocked by the shielding wall on the left, while the target simulator device will be exposed, thus enabling target simulation testing.

[0011] Preferably, the corner reflector is installed in a pull-down manner. When the corner reflector is not needed, it can be pulled down and hidden at the bottom of the right frame and covered with a wave-absorbing material. At this time, the corner reflector is completely hidden at the bottom of the dark box, and only the target simulator device is kept inside the dark box.

[0012] Preferably, the corner reflector is installed in a hinged, concealed manner. When the corner reflector is not needed, it is closed by hinge and laid down to hide at the bottom of the right frame and covered with a wave-absorbing material. At this time, the corner reflector is completely hidden at the bottom of the dark box, and only the target simulator device is kept inside the dark box.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] This device uses a telescopic support rod to raise and lower the angle reflector, or a pull-up / pull-down mechanism, or a hinged, concealed mechanism to raise and lower it. During millimeter-wave radar angle reflector calibration, the angle reflector is raised to the same height as the target simulator. At this height, the angle reflector is higher than the shielding wall, and the absorbing cotton shields the target simulator, preventing signal interference during testing. During millimeter-wave radar target simulation testing, the angle reflector is lowered to the shielding wall, where it is either completely hidden or concealed by the left-side shielding wall, while the target simulator is exposed, allowing for target simulation testing. This solution requires only one shielding box to complete both millimeter-wave radar calibration and testing, reducing the need for a separate shielding box and lowering hardware costs. It also reduces the equipment footprint, energy consumption, and management costs. Attached Figure Description
