Tool system for assembling, transferring and near-field testing of large phased-array antenna

Abstract

The invention relates to the field of large phased-array antenna tool systems, in particular to a large phased-array antenna assembling, transferring and near-field testing tool system. The system comprises a platform frame, a walking mechanism, a pitching mechanism and a posture adjusting mechanism, wherein the walking mechanism is arranged at the bottom of the platform frame and used for drivingthe platform mechanism to move; the posture adjusting mechanism is arranged on the platform frame, the pitching mechanism is arranged on the posture adjusting mechanism, the posture adjusting mechanism is used for adjusting the azimuth angle and the rolling angle of the pitching mechanism, and the pitching mechanism is used for supporting an antenna and adjusting the pitching angle of a strip line. The beneficial effects of the invention are that the method can meet the application demands of the whole process from the assembly, transfer to near-field testing of a large phased-array antenna,achieves the automation and precision of the assembly, adjustment and testing of the phased-array antenna, improves the assembly and integration efficiency and product quality of the antenna, reducesthe manual labor intensity, and improves the production safety.

Description

technical field [0001] The invention relates to the field of large-scale phased array antenna tooling systems, in particular to a large-scale phased array antenna assembly, transfer and near-field testing tooling system. Background technique [0002] During the phased array antenna assembly, integration and testing process, according to the process requirements, it is necessary to support, attitude change, transfer and precise positioning of the phased array antenna during near-field testing. Specifically, it includes using the sky crane for auxiliary installation of the pole to support the antenna through the pole. Before the near-field test in the darkroom, the position and posture of the assembly tool need to be adjusted to ensure the relative position to the probe. [0003] For phased array antennas, especially large phased array antennas, the existing tooling systems and methods mainly have the following problems: [0004] 1) There are many types of phased array antenn...
