Abstract :
Fast Multipole Method (FMM) is applied to calculate the backscattering from 1-D Pierson-Moskowitz dynamic conducting sea surfaces and time series of sea clutter scattering amplitude are obtained under different conditions. The best fitting distributions to the sea clutter amplitude for various frequency, incident angles, wind speed and polarization are acquired. Finally, the computing results are analyzed and discussed in detail.
