摘要
分析比较了用于高频电波粗糙海面散射建模的微扰法和广义函数法,以及基于这两种方法所建立的非后向散射模型。结果表明,两种方法所建立模型的物理本质相同,但建模条件和过程不同;Rice微扰法所建模型适用范围更广,可作为任意高频雷达系统的分析基础。
The perturbation method and the generalized function method for scatter modeling, and the non-backscatter model based on the two methods are analyzed and compared. Results show that, although the modeling conditions and the modeling processes based on the two methods are different, the physical essences of the established models are the same. Moreover, the model based on the Rice perturbation method is applicable to a wider range and it can be used as the analysis basis of arbitrary high frequency radar system.
