A NEW METHOD FOR MEASURING OCEAN WAVE FROM SEASAT SAR REMOTE SENSING IMAGE

摘要

A new method for measuring ocean wave length and direction from SEASAT SyntheticAperture Radar (SAR)remote sensing image is presented in the paper. In the new method, an ocean waveimage is sampled in certain directions, the samples are then analyzed by using one dimensional FourierTransformation to calculate the ocean wave correlation function. Finally the ocean wave length and direc-tion are determined from the ocean wave correlation function. The new method is better than the tradition-al two-dimensional Fourier Transformation method in both consuming time and precision .
