本文应用蒙特卡罗法模拟了一维和二维随机粗糙表面,讨论了均方根高度和相关长度对随机粗糙面表面起伏的影响。然后采用基尔霍夫近似方法计算了随机粗糙面的散射系数,比较讨论了均方根高度和相关长度的不同对雷达回波散射系数的影响。
本文應用矇特卡囉法模擬瞭一維和二維隨機粗糙錶麵,討論瞭均方根高度和相關長度對隨機粗糙麵錶麵起伏的影響。然後採用基爾霍伕近似方法計算瞭隨機粗糙麵的散射繫數,比較討論瞭均方根高度和相關長度的不同對雷達迴波散射繫數的影響。

We use Monte Carlo method to simulate One dimension and two dimension rough surface. Sag and swell of rough sur-face decided by correlation length and root mean square height is studed. And then,the scattering coefficient of the surface is calculated byKirchhoff Approximation. In the end,we discuss the scattering coefficient from different rough surface simulated with different correlation length and root mean square height.
