The desktop radar test device 1 includes a test box 10, a rotating table 20, a sliding guide rail 40, a simulated target object 300 and a main control device 50. Among them, the rotating table 20 is installed in the test box 10 and can rotate relative to the rotating table 20; the sliding guide rail 40 is arranged in the test box 10 and is located on one side of the rotating table 20; the simulated target object 300 is installed on the sliding guide rail 40 and can move with the sliding guide rail 40; and the simulated target object 300 is arranged opposite to the radar 2021; the main control device 50 is connected to the test box 10 for communication.

[0030] The test box 10 is rectangular, and is provided with an entrance and an exit and a door 101 for opening and closing the entrance and exit, which is arranged on a short side wall of the test box 10, and handles 102 are arranged on opposite sides. In some feasible embodiments, one or more doors 101 can be arranged, and can be arranged on the long side wall.

[0031] In this embodiment, the test box 10 is paved with an absorbing material 105, which is a wedge shape. It can be understood that in some feasible embodiments, the absorbing material 105 can also be replaced with other shapes, such as a single-layer flat plate shape, a double-layer or multi-layer flat plate shape, a coating shape, etc. The absorbing material 105 absorbs or greatly weakens the electromagnetic wave energy received on its surface, thereby reducing the interference of electromagnetic waves, and has the properties of light weight, temperature resistance, moisture resistance, corrosion resistance, etc.

[0032] Furthermore, a first mounting seat 204 is provided at the bottom of the test box 10 , and the bottom of the rotating platform 20 is rotatably connected to the first mounting seat 204 .

[0033] In this embodiment, the rotating platform 20 is provided with a fixing position 202 for fixing the radar 2021 to be tested. The fixing position 202 is arranged at the top away from the bottom of the test box 10 , and the fixing position 202 rotates with the rotating platform 20 .

[0034] Further, the rotating platform 20 includes two longitudinal arms 203 arranged opposite to each other and a transverse arm 201 connected to the longitudinal arms 203. The radar 2021 to be tested is fixed to the fixed position 202 on the top of the rotating platform 20, and the fixed position 202 of the radar to be tested is set on the transverse arm 201.

The radar 2021 to be tested is operably placed in the fixed position 202 or taken out from the fixed position 202 through the box door 101.

[0035] In this embodiment, the sliding guide rail 40 includes an inner sleeve 403 , an outer sleeve 402 and a slider 401 , and the sliding guide rail 40 is slidably mounted with a second mounting seat 301 .

[0037] The simulated target object 300 is a cone with its bottom facing the radar, mounted on the end of the second mounting seat 301 away from the sliding guide rail 40 , and arranged opposite to the radar 2021 .

[0038] In this embodiment, the simulated target object 300 is a corner reflector device. After the electromagnetic wave of the radar 2021 to be tested scans the reflection angle of the simulated target object 300, the electromagnetic wave will be refracted and amplified on the metal corner, generating a strong echo signal and a strong echo target. In some feasible embodiments, the user can replace the simulated target object 300 on the second mounting seat 301 with a reflector of a different model.

[0039] In this embodiment, the main control device 50 is connected to the desktop radar test device 1 through a plurality of interfaces 103 to control the communication connection with the desktop radar test device 1. The test box 101 is provided with one or more interfaces 103, and the interface 103 is a wireless interface or a wired interface. The main control device 50 can also be directly connected to the test radar 2021 through the desktop radar test device 1. The wired connection method between the desktop radar test device 1 and the main control device 50 or between the test radar 2021 and the main control device 50 through the test box 10 can be a serial port, a network cable, etc., and the wireless connection method can be WIFI, Bluetooth, etc.

[0040] Further, the main control device 50 is used to generate corresponding test instructions according to a preset test program. The test instructions include distance test instructions for controlling the radar 2021 to be stationary relative to the simulated target object 300 in the working state, and obtaining the distance measurement data returned by the radar 2021; or controlling the rotating platform 20 to drive the radar 2021 to rotate 300 relative to the simulated target object when the radar 2021 is in the working state and obtain the angle measurement data returned by the radar 2021, or controlling the sliding guide rail 40 to move when the radar 2021 is in the working state and obtain the speed measurement data returned by the radar 2021. The distance measurement data, angle measurement data, and speed measurement data are used to calculate the test result of the radar 2021.

[0041] When the desktop radar test device is used for testing through the control of the main control device 50 , the door 101 located at one side of the test box 10 is first opened, the radar 2021 to be tested is fixedly placed on the rotating table 20 , and the door 101 is buckled.

[0042] The test command is executed on the main control device 50. After the test parameters of the qualified radar are input in advance, the main control device controls the desktop radar test device 1 to perform the test:

[0043] The main control device 50 obtains the distance, energy and other values ​​of the target detected by the test radar 2021 in the initial state through the interface 103, and compares them with the preset parameters. If the test value is within the threshold range, the test radar 2021 passes the test and enters the next test link; if the test value is not within the threshold range, the test radar 2021 fails and exits the test.

[0044] The main control device 50 controls the two longitudinal arms 203 of the rotating platform 20 to rotate in the horizontal direction relative to the first mounting seat 204 through the interface 103, obtains the distance, angle, energy and other values ​​of the current detection target of the test radar 2021, and compares them with the preset parameters. If the test value is within the threshold range, the test radar 2021 passes the test and enters the next test link; if the test value is not within the threshold range, the test radar 2021 fails and exits the test.

[0045] The main control device 50 controls the horizontal arm 201 of the rotating platform 20 to flip relative to the longitudinal arm 203 through the interface 103, obtains the distance, angle, energy and other values ​​of the target currently detected by the radar 2021, and compares them with the preset parameters. If the test value is within the threshold range, the test radar 2021 passes the test and enters the next test link; if the test value is not within the threshold range, the test radar 2021 fails and exits the test.

[0046] The main control device 50 controls the second mounting seat 301 to slide a certain distance along the track 404 at a constant speed through the interface 103, obtains the speed, energy and other values ​​of the target currently detected by the radar 2021, and compares them with the preset parameters. If the test value is within the threshold range, the radar 2021 passes the test and enters the next test link; if the test value is not within the threshold range, the radar 2021 fails and exits the test.

[0047] When the test radar 2021 passes all the above test items, the radar 2021 test passes; otherwise, it fails, the main control device 50 issues a warning reminder and reason, and the test ends.

[0048] In the above embodiment, the desktop radar test device sends corresponding test instructions through the main control device, such as controlling the static state of the radar to be tested relative to the target simulation object or the working state of the radar to be tested relative to the target simulation object. At the same time, the test data returned by the radar to be tested under different conditions is obtained through the return data of the target simulation object, and the test results required by the radar to be tested are calculated, so that the test efficiency is increased, the complexity of the experimental operation is greatly reduced, and the influence of human operation during multiple experiments is reduced.

[0049] Obviously, those skilled in the art can make various changes and modifications to the present application without departing from the spirit and scope of the present application. Thus, if these modifications and variations of the present application fall within the scope of the claims of the present application and their equivalents, the present application is also intended to include these modifications and variations.

[0050] The above examples are only preferred embodiments of the present application, and certainly cannot be used to limit the scope of rights of the present application. Therefore, equivalent changes made according to the claims of the present application still fall within the scope covered by the present application.
