Research of Airborne Radome Electrical Thickness Measurement System Control Algorithms

The Airborne Radome Electrical Thickness Measurement System (ARETMS) is designed to detect the electric thickness of the radome with irregular complex rotation. The ARETMS contains vertical lifting axis. The system uses the double horn transmission method in the measurement process. The digital and analog files of airborne radome are processed by discretization. The ARETMS transforms the three-dimensional coordinates into the coordinates of the five-axis machine tool through coordinate transformation and projection. In this study, the system establishes a virtual axis, which keeps correlation with five real axes to work synchronously. The ARETMS improved the accuracy and efficiency of radome electrical thickness measurement greatly, and figured out the nonconforming area which could help to fix the radome.
