一个启发式的粗糙表面散射模型，并从模型粗糙表面获得的实验结果进行了比较。理论模型是从单独的计算的散射场的相干和非相干部分。这使得理论和实验的相干和非相干散射系数之间的直接比较。该模型是一致的，因为零粗糙度和大尺度粗糙度的正确的限制形式。非高斯表面统计被纳入模型中，由此产生的理论预测与镜面和前向散射实验数据密切一致。
A heuristic rough‐surface scattering model is given and compared with experimental results obtained from model rough surfaces. The theoretical model is developed from separate calculations of the coherent and incoherent parts of the scattered field. This allows a direct comparison between theoretical and experimental coherent and incoherent scattering coefficients to be made. The model is consistent in that the correct limiting forms for zero roughness and for large‐scale roughness are obtained. Non‐Gaussian surface statistics are incorporated in the model and the resulting theoretical predictions agree closely with specular‐ and forward‐scattering experimental data.
