Description

[Technical field]

[0001] The present invention relates to a computer-implemented method for determining the alignment of components in an over-the-air test chamber, in particular a CATR chamber.

[0002] The present invention further relates to a system for determining the alignment of components in a wireless test chamber, in particular a CATR chamber.

[0003] Additionally, the present invention relates to a computer-implemented method for testing components in a wireless test chamber, particularly a CATR chamber.

[0004] Still further, the present invention relates to a wireless test chamber, in particular a CATR chamber. [Background technology]

[0005] The End-of-Line (hereinafter also referred to as "end of production line")-CATR test system for radar sensors performs automated inspection and calibration of mass-produced radar sensors used in vehicles.

[0006] At the production line final test stand for mass-produced automotive radar sensors, it is necessary to check the functionality of the fully assembled module and perform an automated calibration using radar target simulation, especially in a small, low-reflection absorber chamber. The measurement of the operating parameters of the radar sensor (hereinafter also referred to as "radar under test") and its calibration are carried out in a defined test procedure, in which the radar sensor is rotated horizontally and vertically around its irradiation central axis by means of a high-precision drive.

[0007] The test piece or the radar to be tested is placed in the test system manually or by a robot in a test piece receptacle protected by a light curtain. There, the sensor is fixed and the sensor type and position are controlled by a barcode. The electrical terminals are then mechanically contacted and the sensor is moved into the absorber chamber, which is closed by an absorber partition.

[0008] Within this absorber chamber are a robot performing relative motion about its central axis of illumination, a reflector having a parabolic surface contour, and a transmitting and receiving antenna of a target simulator within the focus of the reflector.

[0009] In this case, the reflector focuses the radar waves emitted by the radar sensor and deflects them onto the receiving antenna of the target simulator. The radar target simulator targets the radar waves and feeds the manipulated radar waves back to the test piece as echoes via the reflector. Since the resulting flat wavefront does not depend on the sensor's inherent far-field distance, the CATR method allows for compact construction forms instead of very large test chambers (often more than 10 m long).

[0010] During the inspection and calibration of the radar sensor, the radar sensor is rotated horizontally (azimuth) and vertically (elevation) around its center of illumination, thereby capturing antenna diagrams with power levels at each angle. The transmit and receive antennas of the radar sensor are then characterized and measured. Functional results such as properly identified targets and their properties can be output as test results, as well as captured features of the respective test pieces.

[0011] US Patent No. 10536228 discloses a test system for testing a device to be tested on the floor of a test chamber, the test system includes a measurement antenna mounted on the floor or side wall of the test chamber, where the measurement antenna is designed to transmit an outgoing test signal to the device to be tested and receive an incoming test signal from the device to be tested, and the test system includes a reflector mounted on the ceiling of the test chamber, where the reflector is designed to collimate the test signal transmitted from the measurement antenna in the direction of the device to be tested, thereby achieving homogeneous illumination of the device to be tested. The reflector is further designed to focus the test signal transmitted from the device to be tested in the direction of the measurement antenna, where the high frequency waves run parallel to each other between the test piece and the reflector, but the side wall of the test chamber is not covered by the test signal, and the reflector focuses the high frequency waves emitted from the test piece on the measurement antenna, where the signal paths of the outgoing test signal and the incoming test signal run vertically between the device to be tested and the reflector.

[0012] Thus, a need exists for improvements in existing methods and systems for testing components in wireless test chambers to enable determination of optimal CATR configurations with respect to development parameters of footprint, structure height, and DUT motion. Summary of the Invention [Problem to be solved by the invention]

[0013] It is therefore an object of the present invention to provide a computer-implemented method and system for determining an arrangement of components of a wireless test chamber, in particular a CATR chamber, that allows for an optimal CATR arrangement with respect to the development parameters of footprint, structure height, and DUT movement.

[0016] The initial arrangement, as used herein, corresponds to a previous or conventionally used arrangement of components within a radio systems test chamber, particularly a CATR chamber.

[0017] Further, the method includes determining optimized alignment position data of components relative to one another within the wireless test chamber and / or optimized alignment position data of groups of components within the wireless test chamber.

[0026] The present invention still further relates to a wireless test chamber, in particular a CATR chamber, for testing components.

[0027] The wireless system test chamber comprises components arranged in the wireless system test chamber, in particular a radar sensor, a reflector and a target simulator, wherein the wireless system test chamber is configured to test the components using a second data set of optimized arrangements of the devices to be tested in the wireless system test chamber, in particular a radar sensor, a reflector and a target simulator or a transmitting / receiving device of the target simulator and / or a second data set comprising positions of groups of optimized arrangements in the wireless system test chamber by the method according to the invention for determining an arrangement of the components of a wireless system test chamber, in particular a CATR chamber.

[0029] Furthermore, the invention also relates to a computer-readable data carrier with a program code of a computer program for performing at least one of the methods according to the invention, when the computer program is run on a computer.

[0030] One consideration of the present invention is to allow more degrees of freedom in the design of the CATR chamber by positioning the basic elements of the CATR array within the chamber differently from one another and by allowing the group as a whole to be optimally aligned by rotation.

[0031] The invention further makes it possible to find the optimal CATR arrangement with respect to the development parameters of footprint, construction height and motion of the radar under test, whereby the arrangement of the components determined under optimization of the CATR arrangement is determined in space relative to one another.

[0046] This advantageously allows maximum flexibility in terms of positioning the optimized array groups within the wireless test chamber.

[0047] According to a further preferred development, the method comprises that the wireless test chamber includes or is operatively connected to a robot, the robot being configured to rotate the radar sensor by a preset angle around the projection axis of the radar sensor during the test process.
