Abstract
In this paper, the two-scale model method, which is much applicable to the comp utation of the electromagnetic scattering field from the rough sea surface, is used to calculate the backscattering cross-section of the one-dimensional time-varying fractal rough sea surface, the related results are also compared with those calculated by small perturbation method. The fractal characteristic of the Doppler spectra of the backscattering signal from the sea surface is studied, th e dependances of the the backscattering cross-section and the width of Doppler s pectra on the incident angle and fractal dimension are also analyed. Finally, th e relationship between the central frequency of the Doppler spectra and the Brag g resonant frequency is discussed in detail.
