RADIO DIRECTION FINDING OVER A TROPOSCATTER PATH. PART 1. GENERAL DESCRIPTION

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 1/10 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.
