【摘要】 超宽带雷达是一种用途广泛的新体制雷达,它与经典雷达有着很大的差异。为了有效地分析和设计超宽带雷达系统,有必要建立超宽带雷达系统模型。雷达系统建模中最重要的工作是仿真雷达目标及环境。本文,我们基于时域有限差分法(FDTD),提出了一种雷达目标的仿真算法,并根据这种算法,仿真了几种简单几何形状的雷达目标实例。在第三节,介绍了一种仿真超宽带海杂波的方法。更多还原

【Abstract】 Ultra -wideband radar is a new-concept radar of many uses.Thcre are large differences between ultra wideband radar and conventional radar.lt is desired to model ultra-wideband radar system.The most important work in modelling radat system is to simulate radat targets and environment.This paper proposed a simulation algorithm of radar targets based on the finite-difference time-domain method.Some simulation results are obtained by the algorithm.In section IE .a method of simulating ultra wideband sea clutter is introduced.更多还原
