Novel optical calibration equipment of radio-frequency simulated target antenna array

The invention discloses novel optical calibration equipment of a radio-frequency simulated target antenna array. The equipment is composed of a laser range-measurement system mounted on a rotary table, a video image acquisition system and a computer control and communication system, wherein the laser range-measurement system is used for measuring the distance between an antenna and the center of the rotary table; the video image acquisition system is used for obtaining an optical image of the antenna and converting the optical image into an electronic image; and the computer control and communication system is used for controlling the turning positioning of the rotary table, receiving the electronic image generated by the video image acquisition system and displaying the electronic image on a screen. Through adoption of the equipment provided by the invention, a mounting position and a spacing of a geometric center of each antenna surface meet design precision requirement, so that the difference in amplitude-phase characteristics among all paths of radiation signals of radiation interfaces of all antenna units is reduced and the fine adjustment of an electric characteristic becomes convenient so as to reach the consistency of electromechanical characteristics. Furthermore, through functions of voice communication and image transmission, workers can accurately obtain measured data and image information of the rotary table in time and the antenna can be conveniently and efficiently adjusted.
