Atmospheric Effects for Ground Target Signature Modeling. 2. Discussion and Application of a Generalized Molecular Absorption Model

Abstract

The report is a detailed discussion of the five-parameter generalization of the Zachor molecular absorption model proposed by Gibson and Pierluissi, and applies that model to a horizontal path of water vapor data. This application covers the spectral intervals of 1200 to 2200/cm and 4900 to 5800/cm with a resolution of 50/cm. The five parameters of the model are determined for each frequency, and the transmission is calculated and plotted. The results of this application are then qualitatively compared to results obtained from the modified King's function which is used in the Air Force Cambridge Research Laboratory (AFCRL) transmittance model. The transmittance values calculated with the use of these models are compared to the original data which were used in the development of the models.
