Embodiment Construction
[0045] In order to make the purpose, technical solution and advantages of the present application clearer, the present application will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present application, and are not intended to limit the present application.
[0046] It can be understood that the terms "first", "second" and the like used in this application may be used to describe various elements herein, but these elements are not limited by these terms. These terms are only used to distinguish one element from another element. For example, a first direction could be termed a second direction, and, similarly, a second direction could be termed a first direction, without departing from the scope of the present application. Both the first direction and the second direction are directions, but they are not the same direction.

The invention relates to an antenna test system and method, a millimeter wave radar and a computer readable storage medium, and the system comprises an experiment camera obscura which is used for providing a physical test environment; a transmitting antenna assembly which is arranged in the experimental camera obscura and used for generating and transmitting a single-tone signal of any frequency point in a first frequency band under the action of the first control signal; a to-be-tested antenna assembly which is arranged in the experimental camera obscura, and is used for keeping a preset angle in a first direction, rotating in a second direction under the action of a second control signal, and receiving a test signal corresponding to the single-tone signal at a different second directionangle in the rotating process; and test equipment which is connected with the transmitting antenna assembly and the to-be-tested antenna assembly, and is used for generating a first control signal anda second control signal and measuring the test signal to obtain a test result. According to the application, the transmitting antenna assembly and the receiving antenna assembly working in the w waveband are arranged in the dark box with a relatively small size, so the cost of the system is reduced while the antenna test performance is ensured.
Description
technical field [0001] The present application relates to the technical field of millimeter-wave radar, and in particular to an antenna test system and method, millimeter-wave radar and a computer-readable storage medium. Background technique [0002] Millimeter-wave radar is a high-precision sensor that measures the relative distance, relative speed, and orientation of the measured object. It was used in the military field in the early days. With the development and progress of radar technology, millimeter-wave radar sensors began to be used in automotive electronics and drones. Intelligent transportation and other fields. The millimeter-wave antenna is a traditional Chinese medicine component of the millimeter-wave radar. The antenna test system is used to test the performance of the millimeter-wave antenna and is often placed in a microwave anechoic chamber. [0003] However, for the vehicle-mounted millimeter-wave radar antenna, the vehicle-mounted radar works in the W-...
