Abstract

Abstract:

Angle jump occurred during the process of rotated of the antenna control unit maintenance. To address this problem, the acquisition and decode process of antenna angle were analyzed to investigate the limitations of the current use of binary combination coding algorithm. In this paper, the reason for the occurrence of code hopping when the phase difference of coarse and fine code exceeded the correctable range was theoretically analyzed, and an improved combination algorithm of rough and residual numbers and precise extremum was proposed. The theoretical analysis and simulation results showed that the error correction ability of the new algorithm was twice that of the binary combination coding algorithm.

Key words: azimuth angle, angle hopped, resolver, antenna control unit, angle combination algorithm, angle coding
