| 摘 要： | 对两种形状较为复杂的军用目标缩比模型的电磁散射特性进行了仿真计算和实验,研究了复杂金属目标的电磁散射时域算法,提出了解决MOO算法求解目标瞬态散射稳定性的方法.给出了一种实验测量模型与数据处理方案.将仿真和实验得到的时域散射场数据解卷积分别与利用MOM计算的目标频域散射场数据进行比较,结果表明:在一定的频域范围内仿真与实验结果较好地保持了一致,从而验证了算法的有效性和实验正确性.

| Abstract: | Electromagnetic scattering characterization of two complex military target models were simulated and measured in this paper. Simulation method of electromagnetic scattering in time domain was investigated and a new method to treat the instabilities of MOO for transient scattering was proposed. A measure method and a data processing scheme for experiment of electromagnetic scattering were recommended. By comparing the results computed by MoM with Fourier transform of a time domain MOO and measured data, the validity of the method presented was proved. |
