Paper Abstract

The emitted and reflected contributions to infrared sea radiance are affected by factors such as water temperature, prevailing weather conditions, wave structure, and viewing geometry. These factors are all addressed in the computer code SYNSEA which generates synthetic IR sea background imagery. In generating a radiance value for a scene pixel, SYNSEA calculates the radiance contributions for a distribution of surface orientations, weights these contributions according to the probabilities with which the orientations will occur, and sums the weighted contributions. SYNSEA predicts a unique surface orientation distribution for each pixel based upon the IFOV and the randomness of the surface, allowing the radiance calculations to make a smooth transition between the extremes of high and low resolution. SYNSEA has been coded in a modular fashion to facilitate modifications for integration with other codes. Although the statistics of the clutter predicted by SYNSEA have not yet been compared to any measurements, mean radiance values predicted with SYNSEA calculations have compared well with radiometric measurements.
