The analysis on Doppler spectrum of 2-D sea clutter in multi-band

Multi-band Doppler spectrum of radar clutter at there-dimensional sea surface is calculated in this paper, the Elfouhaily sea spectrum with a direction function is applied to achieving the scattering fields is a classic PO method. Analysis on the spectrum width and shift of multi-band can be done. Larger spectrum width and shift have been seen in larger wind speed in high frequency. By applying the Doppler model to the data, it is possible to extract the Bragg scattering polarization ratio, and the two non-Bragg scattering mechanisms can also be studied, this is what the process in this paper means.
