Paper Abstract

Since target information can be extracted from the light scattering distributions, light scattering from randomly rough surface has been studied in details. As numerical light scattering computation methods can provide precise information avoiding complicated operations and expensive experimental setups, various numerical methods have been widely used. However, most of them require ensemble average computation to obtain the stable results, inevitably decreasing the calculation efficiency. In order to further accelerate the processing speed by avoiding the ensemble average calculation, a high speed method based on surface slope probability density function is designed in this paper, which using the statistical parameters of randomly rough surfaces for direct light scattering calculation. With numerical simulations proving its high accuracy and rapid speed in light scattering computation, the slope probability density function based method is a potential tool for light scattering computation and analysis.
