MICROWAVE PORTION OF THE OXYGEN LINES REFRACTOMETER

Abstract

A microwave subsystem was installed in The MITRE Corporation's refractometer vans as an integral part of the oxygen-lines refractometer. In operation, two coherent frequencies, 45 and 90 Gc, are transmitted along a 23-km path, and the change in differential phase shift is measured at the receiver. This change is an indication of the refractive qualities of the atmosphere over the path. The equipment was tested at a field site in the Lake Winnepesaukee, New Hampshire, region; test results and recommendations for improving system sensitivity and stability are given.
