Abstract

In order to explore how to etch high-precision FSS units on the surface of large-scale variable curvature non-expandable radome, this study designed and constructed a complete set of curved FSS laser etching systems. In the process of platform construction, by comparing the processing methods of various FSS, a galvanometer laser scanning system with high processing accuracy and efficiency was selected and equipped with a servo motion system. The proposed system can realize high-precision laser etching processing of frequency selection surface and thus provide a reference for other similar projects and practical applications.
