中文摘要：
采用空间域合成法生成高度起伏遵守Alpha-stable分布的粗糙土壤表面,运用矩量法研究了锥形入射波入射时粗糙土壤表面的电磁散射特性。数值计算了散射系数随散射角的变化关系,分析了稳定性系数、归一化尺度参数、互相关长度、入射波频率、土壤湿度对散射系数的影响。结果表明,稳定性系数、归一化尺度参数、互相关长度、入射波频率、土壤湿度对散射系数均有较大的影响,遵守不同的规律。
英文摘要：
The spatial domain building method is used to generate rough soil surface with Alpha-stable distributions, the characteristic of electromagnetic scattering from rough soil surface in the condition that the tapered wave incidence by using method of moment. The varying relationship of scattering coefficient with scattering angle is numerical calculated, the influence of the stability coefficient, normalized scale parameter, cross correlation length, the incident wave frequency, and moisture of soil on the scattering coefficient is analyzed. The results show that the influence of the stability coefficient, normalized scale parameter, cross correlation length, the incident wave frequency, and moisture of soil on the scattering coefficient is obvious, and the different laws are obeyed.
