Theory and Measurements of Angle-of- Arrival of Diffraction-Limited Electromagnetic Wave Beams in the Turbulent Atmosphere

Abstract

Atmospheric turbulence has been shown to have measurable effects on the angle-of-arrival (AOA) of electromagnetic wave beams, but these effects are on the order of a few microradians, which is a negligible level for most applications. In this paper, we present a theory describing this phenomenon and compare this theory to one-way measurements made over a 3.5 km path and two way measurements made over a 25 km path using an Xband interferometric radar.
