摘要

用指数高度相关函数研究了统计粗糙表面合成孔径下平面波和雷达信号的反射。利用高斯函数的叠加提出了相关函数的近似。这使得开发一种有效实用的雷达回波模拟算法成为可能。根据已知的随机表面漫射波反射渐近规律对结果进行了验证。所提出的计算方法可以广泛应用于不同构型波源的稳态和瞬态波场从本文所考虑的类型的粗糙表面反射的情况。

Calculation of Radar Reflections from Exponentially Correlated Surfaces

We study the reflection of plane waves and radar signals with synthesized apertures from statistically rough surfaces with an exponential height correlation function. Approximations of the correlation function are proposed using superpositions of the Gaussian functions. This makes it possible to develop an effective practical algorithm for simulating radar echoes. The results are verified against known asymptotic laws for diffuse wave reflection from random surfaces. The proposed computational approach can be applied in a wide range of situations where the stationary and transient wave fields from wave sources of different configurations are reflected from rough surfaces of the types considered here.
