摘要

研究了奇异展开法识别天线的灵敏度。以偶极子天线为研究对象，采用矩阵笔法对其背散射场进行了分析。然后，在偶极子天线上施加长度、直径和负载阻抗的微小变化，并分析了复平面上极点的变化。结果表明，极提取对窄带偶极子天线的尺寸和负载阻抗非常敏感。

Sensitivity of the singularity expansion method applied on dipole antenna backscattering

This paper deals with the sensitivity of the singularity expansion method to identify antennas. A dipole antenna is considered and the matrix pencil method is applied on its backscattered field. Then, small variations of length, diameter and load impedance are applied on the dipole antenna and the variation of poles in the complex plane is analyzed. It shows that pole extraction is very sensitive to the dimensions and load impedance of the narrow band dipole antenna.
