海面（或地面）环境中目标电磁散射特性，对实际战场环境下军用目标的雷达探测、雷达特性形成以及雷达目标识别等技术具有基础支撑作用。因此，快速准确地分析目标和粗糙面复合电磁散射特性具有重要理论意义和应用价值。文章采用基于矩量法（MOM）和物理光学法（PO）的混合方法MOM-PO分析了目标和粗糙面复合电磁散射问题。与传统的矩量法相比，该方法在保证精确度的前提下大大加快了计算速度。

Electromagnetic scattering characteristics of the targets on sea (or ground) has wide applications in ra-dar detection, radar characteristics form and radar target recognition technology for military targets on actual bat-tlefield environment. Therefore, fast and accurate analysis of composite electromagnetic scattering from target and rough surface combined model has important theoretical significance and application value. In this paper, based on the method of moment (MOM) and physical optics (PO) method of hybrid method MOM - PO, the target and rough surface composite electromagnetic scattering problems were analyzed. Compared with the traditional method of moment, in the premise of guarantee accuracy, the method greatly accelerated the calculation speed.
