Angle of Arrival Calculations at 10.6 microns
Abstract
The report deals with the specification of the angular position of objects by measurement of the angles of arrival of light beams; and with the measurement uncertainties due to atmospheric turbulence. A survey of the literature is presented showing two approaches to angle of arrival, one for large aperture receivers and one for a single small aperture or a pair of pinholes. Pertinent defining equations are presented for both cases and values are calculated for arrival angle mean square measured with a large aperture and correlation of arrival angles for small apertures. A synonymity between the small correlation function and large aperture mean square angle of arrival is presented and used to present further large aperture mean square values. This provides a significant simplification in calculation and measurement capabilities. Finally the regions of accuracy are presented for the Rytov approximation which forms the basis for the numeric calculations.
