With the same current and wind, results show that the stochastic multi-scale model agrees with the improved composite surface model and both of them are better than the Bragg model because the latter one underestimates the radar backscattering.
本文也分析了散射模型(布拉格模型,改进组合表面模型,随机多尺度模型)对SAR成像的影响,结果表明:相同流场、风场输入的情况下,改进组合表面模型和随机多尺度模型的仿真结果较为一致,均优于布拉格散射模型,后者后向散射系数值偏小。
