Abstract

The invention discloses a test method and device of a vehicle-mounted phased-array antenna and electronic equipment. On one hand, whether a test result of an antenna is reliable or not is obtained according to a difference value between a theoretical value and an actual value of each characteristic parameter, and on the other hand, the performance of the antenna is further obtained through the size of effective radiation power. Therefore, the antenna can be tested from the two aspects of the characteristic parameters of the antenna pattern and the effective radiation power of the antenna, and compared with traditional manual testing, the testing method provided by the embodiment of the invention is higher in precision, smaller in error and more suitable for testing the vehicle-mounted phased-array antenna.

Description

technical field [0001] The invention belongs to the technical field of vehicle-mounted phased array antennas, and in particular relates to a testing method, device and electronic equipment for vehicle-mounted phased array antennas. Background technique [0002] With the rapid development of electronic technology and the deepening of electromagnetic research, the antenna, as an indispensable key component for signal reception and transmission, has been used in many fields such as navigation, communication, aviation and automobiles, and has become one of the indispensable components of modern communication. ; As a derivative technology of traditional antennas, the vehicle-mounted phased array antenna has become the focus of modern communication development because of its advantages of flexible control of beam shape and rapid switching of beam direction. [0003] Equipment for different purposes often requires antennas to have different performance requirements. Therefore, the ...
