Measurements of Optical Turbulence Parameters Aboard the Aircraft Carrier USS LEXINGTON.

Abstract

This report presents measurements of optical turbulence at several locations on board the USS LEXINGTON. Data on C(sq N) were collected during and outside flight operations at three sites using a set of microthermal probes. Background values of C(sq N) were found generally to be 10 to the -15th power/m(2/3) or less while spikes 2 to 3 orders greater are observed during aircraft launch. High values of C(sq N) measured at the hanger bay door are used to estimate a new error for the pointing accuracy of the ship-to-ship tracker due to beam wander. The bulk parameterization model is also used with moderate success to predict background C(sq N). Finally several C(T) frequency spectra are presented and their usefulness discussed.
