Problems solved by technology
Due to the errors of the electronic device itself and the mechanical assembly, the performance consistency of the produced radar products is poor, and it must be calibrated to make the radar performance consistency meet the requirements.
[0003]
The alignment of the radar target simulator and the radar antenna in the existing radar calibration system can only realize the geometric center alignment of the radar target simulator and the radar antenna, but does not realize the alignment of the radar antenna surface and the receiving antenna surface of the radar target simulator. Alignment accuracy is poor

Embodiment Construction
[0031] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. Based on the implementation manners in the present invention, all other implementation manners obtained by persons of ordinary skill in the art without making creative efforts belong to the scope of protection of the present invention.
[0032] It should be noted that when a component is said to be "mounted on" another component, it may be directly mounted on another component or there may be an intervening component. When a component is said to be "set on" another component, it may be set directly on the other component or there may be an intervening component at the same time. When a component is said to be "fixed" to another component, it may be directly...

The invention relates to the technical field of radars, in particular to a radar calibration system alignment mechanism and an alignment method. The alignment mechanism of a radar calibration system comprises a rotary table assembly, a calibration assembly and a tool piece. The rotary table assembly is arranged opposite to the calibration assembly, and the tool piece is installed on the rotary table assembly and used for clamping a radar to be detected; the calibration assembly comprises a substrate, a first laser emitting piece, a second laser emitting piece and a simulator, the substrate isprovided with a first surface facing the rotary table assembly, the first surface is provided with a reference line, and the simulator is provided with a receiving plane parallel to the first surface;a second ray surface and a first ray surface are arranged in an intersecting mode, and the intersecting line of the first ray surface and the second ray surface penetrating through the center of thereceiving plane. The invention also provides a radar target simulator alignment method. The mechanism has the advantages of simple operation and high alignment precision.
Description
technical field [0001] The invention relates to the technical field of radar, in particular to an alignment mechanism and an alignment method of a radar calibration system. Background technique [0002] The radar is installed on the car and can measure the distance, angle and relative speed from the radar to the measured object. Radar is a key sensor for the realization of autonomous driving technology and advanced driver assistance systems. Radar calibration is related to the performance of the radar and also to the reliability of the entire advanced driver assistance system. Due to the errors of the electronic device itself and the mechanical assembly, the performance consistency of the produced radar products is poor, and the radar performance consistency must be calibrated to meet the requirements. [0003] The alignment of the radar target simulator and the radar antenna in the existing radar calibration system can only realize the geometric center alignment of the ra...
