摘要
主要针对雷达目标极化特性建模问题开展相关研究,提出了一种利用SolidWorks虚拟装配技术构建目标几何模型,再利用FEKO电磁计算软件计算目标极化散射矩阵建模方法。采用该方法分别对典型舰船目标、飞机目标及角反射体进行了几何建模,并以舰船目标为例,详细介绍了极化散射矩阵求解过程,计算结果表明舰船在不同角度的主极化比交叉极化变化值差异很大,其变化趋势同实际测量情况基本一致。提出的雷达目标极化特性建模方法对于提高目标极化模型逼真度和仿真置信度具有重要意义。
This paper mainly researches the modeling problem of radar target polarization, proposes the use of a Solid- Works virtual assembly technology to construct the target geometry model, then calculate the software to calculate the target scattering matrix using FEKO electromagnetic modeling method. By using the method of typical ship targets, respectively and the target plane reflector geometry modeling, and the ship as an example, introduces in detail the polariza- tion scattering matrix calculation, the calculation results show that the ship at different angle than the main polarization cross polarization change value difference is very large, the trend is basically consistent with the actual measurements. The modeling method of polarization characteristics of radar target proposed in this paper is important for improving the fidelity of target polarization model and simulation confidence.
