Monte-carlo simulations for SAR imagery of Two-dimensional ocean waves
Synthetic aperture radar (SAR)have been an extremely valuable tool to study, observe and surveillance the ocean states. In contrast to a stationary scene, the imaging mechanisms of ocean wave are more complicated due to stochastic character of its orbit motions and wind effect. The relationship between SAR imagery and the actual ocean waves is an intriguing issue. Simulations can gain good insight into interpreting the physical aspect questions. A straightforward method for dealing with the ocean-SAR mapping transform is to compute the SAR image with pixel-by-pixel. Monte-carlo simulations have been proposed for this purpose. In the framework of monte carlo simulation methods, two-dimensional JONSWAP ocean wave spectrum with spreading function is developed; Under two kinds of sea states, i.e., a fully developed wind sea and a growing wind sea, we simulated the ocean-SAR mapping transform and some meaningful results are exhibited and discussed.
