Abstract

An idea to explore fractal structures in the field of ocean microwave radiance is suggested. To solve this problem we must be able to relate natural ocean surface features to their thermal microwave emission signatures. This task has two problems: (1) the study of hydrodynamic fractal structures in the ocean, and (2) the creation of an adequate microwave imaging model. One possibility is to consider a fractal model of the ocean surface with scaling (power law) wave number spectra. Microwave emission effects from a rough water surface are calculated quite using a small-perturbation approach well known in the ocean passive microwave radiometry. Combined computer simulations allow us to generate microwave fractal images and local patterns. Some related experimental data have been found previously during polarimetric scanning radiometer measurements
