Abstract

Microwave backscattering from sea surface at low grazing angle (LGA) is important in predicting radar detection of targets on or near the surface, since the probability of a false alarm depends upon the observed signal-to-clutter ratio. However, the large area illuminated by incident beam at LGA leads to a number of unknown when using numerical method to calculate backscattering from sea surface. In addition, the calculation of backscattering from hundreds of random sea surface samples is needed to obtain the statistical properties of random rough surface. The sparse matrix canonical grid (SMCG) and compute unified device architecture (CUDA) libraries are used to accelerate the computation. By using these techniques, Doppler spectral characteristics of electromagnetic scattering from sea surface is effectively calculated.
