BACKSCATTER SIGNATURE STUDIES FOR HORIZONTAL AND SLANT RANGE VISIBILITY.

Abstract

Results are presented of a study of backscatter signatures indicative of horizontal and slant visual range. The physics of the concept is described in terms of mathematical relationships between the backscatter signatures and the atmospheric extinction coefficient. An experimental program is described which tests the backscatter signature concept utilizing a Q-switched ruby laser and an off-axis optical backscatter receiver. The experimental data are compared with transmittance as measured by transmissometers located at the experimental test sites. The results verify and support the prior theoretically-implied behavior of the backscatter signature system. This study indicates that such a backscatter signature system for measuring extinction coefficients is feasible and warrants further investigation. (Author)
