Abstract

The invention discloses a method for detecting the flatness of planar antennas and a fast adjustable tool thereof. The fast adjustable tool comprises a flat plate base, and supporting structure units which are distributed in an array mode are arranged on the flat plate base. Each supporting structure unit comprises a sleeve supporting piece, a supporting piece with the surface being provided with a dividing rule in the sleeve supporting piece, and locking bolts used for fastening the supporting piece. During detection, the flat plate base is arranged in the horizontal plane, the dividing rules on the surfaces of the supporting pieces are used as the reference, the top ends of all the supporting pieces are adjusted to be at the same height, and the supporting pieces are fixed through the locking bolts. A gradienter is used for conducting equal-height calibration on the heights of the top ends of all the supporting pieces, the planar antennas are placed on the supporting pieces, then the position heights of the planar antennas are detected through a measuring instrument, and thus the flatness of the planar antennas is obtained through calculation according to the position heights of the planar antennas. According to the detecting method and the fast adjustable tool thereof, operating is easy and convenient, and the problems of being large in detection workload, repeated in measurement, low in flatness detection precision and quality, and the like at present can be solved.

Description

technical field [0001] The invention belongs to the field of mechanical engineering and antenna application, and in particular relates to a flatness detection method of a flat panel antenna and a fast adjustable tooling thereof. Background technique [0002] With the development of radar antenna technology, when assembling and installing the antenna, it is necessary to detect and calculate the flatness of its flat panel to check whether it meets the technical requirements of the radar antenna. A large assembly gap occurs during surface assembly, resulting in a decrease in the performance of the antenna. Therefore, the flatness of the antenna panel plays an important role in improving the performance of the antenna. During antenna flatness detection and antenna assembly, a fast and adjustable tooling is required for placement and support, which is convenient for detection and adjustment of the height of placement, so that the height of the antenna plate support is consistent...
