摘要
本文介绍了目标宽带电磁散射理论建模采用的目标电磁散射模型以及一维距离像、两维成像等宽带雷达目标特征信号的预测，突破原有的点频 Ｒ Ｃ Ｓ散射理论建模水平；而且本文宽带散射建模进行多频散射计算，反映了宽带雷达工作原理，便于宽带建模数据的进一步处理，进行目标频域特性分析和时频表达．本文最后给出了理论建模实例并与实际测量结果进行比对。
The paper presents a practical method for high frequency electromagnetic scattering modeling used in wideband radar signals prediction and analysis,which is beyond the capability of the narrowband RCS modeling.This method is capable of range profile computation,ISAR imaging.In particular,the electromagnetic scattering mechanism of each scattering center on complex objects can be determined in wideband radar scattering time frequency analysis.Some typical scattering computation results of an aircraft,such as RCSs,range profile,ISAR image,are given.This modeling method shows the validation in comparing with the measured data.
