Measurements of the Beam and Point Spread Functions of Sea Water

Abstract

This report presents the first in situ sea water measurements of the Beam Spread Function (BSF) and Point Spread Function (PSF). Furthermore, these measurements are valid to much smaller angles than those previously published and should be of value in imaging system analysis. Measurements are presented for sea water ranging from clear coastal to maximum clarity deep oceanic; over an angular range from less than .0001 radians to 180 deg and for propagation ranges up to nine attenuation lengths.
