提出了一种新的天线散射分析模型，该模型分别给出了结构模RCS和天线模RCS。该模型解决了两种模式之间难以模拟的相位差问题。从模型结果可以方便地得到任意载荷下天线的散射。利用ANSOFT HFSS软件实现了该模型，并给出了一些有用的结果。将结构模态RCS和天线模态RCS与其他方法的结果进行了比较，验证了模型的正确性和有效性。研究结果对天线RCS的预测和降低具有重要意义。
A novel model is proposed to analyze the scattering of an antenna which gives the structural mode RCS and antenna mode RCS separately. The phase difference between the two modes, which is difficult to simulate, is solved with the model. The scattering of an antenna with arbitrary load is obtained conveniently from the model results. The model is realized by the ANSOFT HFSS and some useful results are illustrated. The structural mode RCS and antenna mode RCS are compared with the results by other methods, which proves the model correct and efficient. The results are meaningful for the antenna RCS prediction and reduction.
