Bidirectional Reflectance Model Validation and Utilization.
Abstract
This report describes a method for using bidirectional reflectance information previously reported in the Eleventh Supplement to the Target Signature Analysis Center: Data Compilation and further validates the bidirectional reflectance model originated and extended under recent contracts. It includes bidirectional reflectance model parameters for a variety of paints. Parameters were extracted from measurement data reported in the Eleventh Supplement. Reduced reflectance data are also provided; these data may be used with the computer model or, optionally, in an interpolation procedure for estimating reflectances without the aid of a computer. The computer model makes it possible to calculate bidirectional reflectance data from a very small amount of measured data. Accuracy demonstrated in the Model Validation section indicates that the model is very effective, although improvement can still be obtained at large receiver zenith angles. The interpolation procedure also shows excellent agreement with measurement. (Author)
