Abstract

This paper describes a quasi-optical calibration switch arrangement that can be used to reduce the demands imposed on the antenna scan motor for passive radiometers. The work addresses the need to replace bulky motor driven scan mechanisms that are currently used on millimetre and submillimetre wave EO radiometers. This will provide a major reduction in payload mass, footprint, power consumption and increase instrument reliability. Key components in the system are electronically reconfigurable Frequency Selective Surface’s (FSS’s) that control the signal transmission to calibration targets and scene radiation in the network. Two switching methods, liquid crystal and piezoelectric actuators have been investigated, and a numerical study carried out on their RF performance
