摘要

本文介绍了带弹和无弹翼杏仁模型后向散射场的设计、分析和数值计算结果。利用Ansys HFSS软件中的物理光学(PO)方法，在1 GHz和9 GHz频段对单站雷达截面(RCS)进行了仿真。利用PO法获得雷达接收到的总散射场分量，将目标体分割成若干个面，然后对这些面散射场分量进行叠加。当目标的电尺寸是波长的两倍时，不考虑阶衍射场。一阶裂缝面积足以计算靶层的RCS。比较了不同频率下带弹翼杏树模型载弹量对RCS的影响。

The analysis of RCS of winged almond model with ammunition and without ammunition

In this paper, the design, analysis and numerical results of back scattering field of winged almond model with ammunition and without ammunition are presented. Simulations with using Physical Optics (PO) method in Ansys HFSS software for monostatic Radar Cross Section (RCS) were made in 1 GHz and 9 GHz. By using PO method to obtain the total scattered field received part of the radar, the body of the target is seperated into number of facets, then all these facets scattered field components are super imposed. When the electrical size of the target is twice as large as the wavelength, the order diffraction field is not considered. The fractured area from the first order will be sufficient to calculate the RCS of the target. Effects of ammunition quantity of modeled winged almon model with ammunition on RCS are compared in different frequencies.
