A GaAs refractometer for tropospheric studies
Abstract
A microwave refractometer designed to be used in studies of multipath propagation on line-of-sight microwave links, and studies of transhorizon ducting is described. The application of a GaAs FET amplifier in a feedback loop containing the sampling cavity produced a lightweight and simple refractometer which was tested and used in a light aircraft with on-board data processing. These various aspects are discussed in some detail, together with the background requirements and specification.
