本文提出一种从seasat合成孔径雷达SAR遥感图象中分析海浪波长和方向的新方法。该方法首先对遥感图象进行定向取样;然后进行一维傅氏变换,求出海浪相关函数;最后求出海浪波长和方向。这种新方法的精度和运算速度明显优于通常采用的二维傅氏变换分析法。 This paper presents a new method for analyzing the wavelength and direction of waves from the seasat synthetic aperture radar SAR remote sensing images. Firstly, the remote sensing image is directionally sampled; then the one-dimensional Fourier transform is performed to find the wave correlation function; finally, the wavelength and direction of the wave are obtained. The accuracy and speed of this new method is significantly better than the commonly used two-dimensional Fourier transform analysis.
