ATMOSPHERIC EFFECTS ON THE BEAM PROPAGATION OF THE XM-23 LASER RANGEFINDER

Abstract

A special optical receiver with a 2-foot input aperture was used to measure beam cross sections of the XM-23 Laser Rangefinder. The standard deviations of the received energies were determined for pathlengths from 200 to 1500 meters. The index structure constant, c sub n (derived from the measured thermal structure function) and the solution to the spherical wave equation were used to predict the standard deviations of the optical energy distributions. The predictions based on meteorological measurements were compared to the standard deviations of the optical measurements for high scintillation conditions.
