Abstract

The invention discloses a method for automatically identifying and calculating antenna pattern pits. The invention provides a special algorithm, and the algorithm can eliminate the interference, caused by a test environment error, of directional diagram small sawteeth on pit recognition, and carries out the precise recognition and calculation of pits. Meanwhile, the calculation process is simple and clear, data processing efficiency is high, and software implementation is facilitated. At present, when engineering application is achieved, the pit processing period in the antenna manufacturing process is shortened by 96%, and the pit recognition efficiency and quality are remarkably improved.

Description

technical field [0001] The invention relates to the technical field of antenna manufacturing, in particular to a method for automatically identifying and calculating pits in an antenna pattern. Background technique [0002] The antenna pattern is an important basis for measuring the performance of the antenna, from which various parameters of the antenna can be calculated and extracted. At present, the antenna pattern data processing business is widely used in the manufacturing activities of various antennas. At present, the pits in the antenna pattern are mainly identified by the naked eye, which is inefficient and easily affected by subjectivity. The existing methods related to pit identification cannot eliminate the interference of the small sawtooth in the antenna pattern caused by the error of the test environment on the pit identification. Therefore, the pit identification method cannot meet the pit identification and calculation requirements of the antenna pattern. ...
