Laser Scattering Phenomenology - Background Signature Characterization And Prediction

An important part of WES's remote sensing program is the development of electromagnetic energy signature maps that vary as environmental conditions change in an area. Such maps are useful for assessing electromagnetic sensor technology since the effectiveness of electro-optical sensors is dependent on weather and terrain background conditions. A model has been developed to predict the laser signatures of various types of terrain backgrounds under selected weather conditions. Experiments have been conducted to calibrate the laser scattering model. This model has been integrated with terrain elevation data and land use maps to produce color displays that indicate terrain areas exhibiting high or low laser scattering. Displays provide researchers with a tool for developing the background signature terrain maps needed to evaluate tactical sensor. technology and delineate specific features of interest.
