Angle-of-arrival of a radar beam in atmospheric turbulence

Atmospheric turbulence has been shown to have measurable effects on the angle-of-arrival (AOA) of radar 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 t...

Zusammenfassung:	Atmospheric turbulence has been shown to have measurable effects on the angle-of-arrival (AOA) of radar 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 X-band interferometric radar.
