| 摘 要： | 描述了一种对改进的IEM模型的扩展双站散射模型。我们发现在非相干功率的表达式中,交叉分量和补充分量都由两项组成:一项与误差函数无关,而另一项与误差函数有关。后一项可看成是由误差函数引起的修正项。模型预测值和测量数据的良好吻合显示了这种扩展双站散射模型的有效性。

| Abstract: | In this paper we propose a bistatic scattering model for electromagnetic scattering from a randomly rough surface,which is an extension to the advanced integral equation model.After lengthy mathematical manipulations,for the cross and the complementary incoherent powers,it is shown that each consists of two terms: one free from and the other related to the error function.The latter can be viewed as a correction term for previous calculations.The validity of this extended bistatic scattering model is demonstrated through the excellent agreements between model predictions and measurement data for statistically known surfaces. |
