摘要
箔条云团数学模型的建立是为了对雷达散射截面进行计算。采用"层-角-角"的划分方法来对箔条云团进行划分,来建立若干个包含箔条云团特性参数的箔条单元体,利用目标与接收点处的功率密度和电场强度对这些箔条单元体有效散射面积进行计算,再将这些箔条单元体的计算结果叠加,同时考虑它们之间的相互作用和阴影效应,最后得出整个箔条云团的雷达散射截面仿真模型。计算表明,该模型可以模拟多种情况下箔条云团RCS值。
The establishment of a mathematical model of chaff cloud is to be calculated on the radar cross section.In this paper,＂Layer-Angle-Angle＂division method to be divided on the chaff cloud,to establish a number of parameters contain clouds of chaff chaff unit body,the use of power density and electric field strength and the reception point target these chaff unit body effective scattering area is calculated,and then the results of these chaff unit body superimposed,taking into account the interaction between them and shadow effects,the conclusion that the whole cloud of chaff RCS simulation model.Calculations show that the model can simulate RCS value chaff clouds many cases.
