摘　　要：建立伪装遮障基础布的二维平面周期结构模型,采用时域有限差分法计算两类导电纤维编织形式(正交和菱形)的基础布对入射雷达波的反射、透射和吸收系数。分析植入的纤维及其编织密度对结构散射特性的影响,并针对某一样网(含基网和装饰布)做数值模拟,分析比较计算结果和测试数据的异同。研究方法和结论可用于散射吸收型防雷达伪装遮障的设计。The two-dimensional planar periodic models of basic cloths of camouflage screen were established. And electromagnetic scattering properties of basic cloths knitted with two kinds of conductive fiber （cross/rhombic form） was calculated by the finite-difference time-domain algorithm. The influences of conductive fiber and its density on scattering properties were analyzed. Numerical simulation of certain sample screen （containing base net and decorative cloth） was made to compare the difference between computed results and test data. These research methods and results can be used to design the scattering and absorbing type anti-radar camouflage screen.
