Statistical Analyses of Selected Terrain and Water Background Measurements Data.
Abstract
Terrain and water background measurement data in the mid-IR have been collected and analyzed in support of the Navy Optical Signature Program. This is a continuing program to provide representative backgrounds data for various system performance studies. Calibrated digital data tapes of the backgrounds data are maintained as part of the program. Selected data over desert and mountainous terrain at Nellis AFB, over a rural and urban terrain in West Virginia, and over water at Pt. Mugu were analyzed in several spectral bands in the IR and mid-IR including 2.0 - 2.6, 3.5 - 3.9, 3.9 - 4.7, 4.5 - 5.5, 5.1 - 5.7, and 9.0 - 11.4 micrometer. Of the extensive data available at Nellis, the data that were selected for statistical analysis provided a comparison of desert and mountainous terrain, downward and 35 degree depression angle data, morning and afternoon data and data at 1000 ft. and 5000 ft. altitude. Statistics and a discussion of the statistical analysis is presented in the report including means, standard deviations, histograms, hot spot (ellipse) analyses, spectral correlations, and power spectra.
