Abstract:

In support of the Light Helicopter Target Acquisition Subsystem TAS DemonstrationValidation conducted at Yuma Proving Grounds, Arizona, during August and September 1991, the US Army Engineer Waterways Experiment Station WES collected field measurements and imagery to characterize site and scene conditions. Meteorological and terrain and target radiometric data were obtained and analyzed. Thermal and visible imagery were obtained within the field of regard during testing of the TAS. Images were processed to compute image metrics relevant to pre-detection image processing by the TAS. Image metrics included target-independent scene metrics, which measure the distribution of selected features over the entire image, and target-specific metrics, which measure specific target features and compute conspicuity of the target relative to the background. Analyses were performed to quantify temporal and spatial variations in metric values over the course of the test.
