Paper Abstract

Ocean clutter in infrared images at low grazing angles is of interest for both airborne and shipborne detection of low flying targets over the ocean. In this paper a 2-D simulation model for infrared cutter at low grazing angle and data analysis results of three IRAMMP ocean tests are presented. The data analyzed correspond to IRAMMP calibrated dual band (mid-wave and long-wave) IR images. The observed ocean clutter is characterized by vertical profiles of the mean and variance, single channel power spectra, and the dual channel coherence as a function of environmental conditions and sensor geometry. The measured variance in radiance typically has a rapid increase with increasing look down angle below the horizon. Preliminary simulation predictions are consistent with data analysis results.
