Abstract

For the past several years the Air Force has been involv..ed with the attempt to measure narrowband atmospheric transmission over horizontal paths (up to 8km) in three spectral regions--visible, 3-5 micrometers and 8-12 micrometers. The data is required for use in LOWTRAN model verification, itself a prime tool for predicting imaging sensor performance as it relates to meteorological conditions. Problems associated with the use of commercially available equipment purchased by the Air Force are briefly described, as well as the design of a new transmissometer receiver intended to operate over the full 8km range. Measurements taken with this new receiver are presented along with their LOWTRAN predictions. Preliminary data indicates that the accuracy attainable with this instrument far exceeds that of the original equipment and will serve as a great help in LOWTRAN validation efforts currently underway.
