| 摘 要： | 提出一种分段插值MBPE技术用于构建天线和散射系统广义系统函数的新思路。分析该系统函数在工作频段内的极点特性,仍可获得系统的广义谐振频率及品质因数。与标准MB-PE技术比较,分段MBPE可将Padé函数降为4阶,有效避免高阶矩阵所带来的矩阵奇异,计算效率低等问题。

| Abstract: | The generalized system function,associated with the radiated or scattered fields is presented in this paper,which is constructed by applying a windowed interpolation model-based parameter estimation technique.By analyzing the characteristics of poles of this system function in the operational frequency band,the resonant frequency and Q-value of the antenna and scattering systems are determined.Compared with the generalized MBPE procedure,this windowed scheme can reduce Pade function to only four orders,which effectively alleviates the problem such as ill-condition,low calculation efficiency etc.caused by high-order matrix. |

| Keywords: | generalized system function MBPE resonance quality factor |
