Abstract:

Measurements of fluctuations from the great circle path to a transmitter in the bearing estimates of a microwave interferometer were made at 910 mc with the transmitter located beyond the horizon. A general description is presented of the apparatus and some experimental results. The standard deviations of the bearing estimates were typically of the order of 110 degree for averaging times longer than 10 seconds, larger fluctuations being observed on over-land than over-water paths due to asymmetries in the cross- path geometry coupled with humidity differences.
