| 摘 要： | 计算单根任意长度箔条的双站散射截面积对于确定混装箔条弹散射截面积具有重要意义。通过建立单根任意长度箔条的散射模型,得出了表征箔条表面电流分布的积分方程;利用矩量法对方程进行求解,得出表面电流分布的数值解;在此基础上,利用电基本振子辐射场公式得到了单根任意长度箔条远区辐射电场表达式,最后利用散射截面积计算公式给出了单根箔条双站散射截面积的数值计算式,并对单根箔条的单双站散射截面进行了仿真分析。

| Abstract: | It is important to calculate the biostatic scattering radar cross section of a thin perfectly conducting chaff to obtain the RCS of a mix-backfilled chaff cannonball. After establishing a reflection model of chaff,an integral equation was got for taking the current distribution of chaff. Then a numerical value was acquired to solve the equation by MOM. After that the expression of chaff radiation field was given. In the end,the calculating formula to compute biostatic scattering radar cross section was presented,and the simulating result of the average backscattering and biostatic radar cross section of chaff was shown. |
