S参数的损耗因子及数据处理
发布时间：2019-06-27 12:58
【摘要】：在二端口微波网络测量过程中,随机误差是引起测量误差的主要因素之一,并导致S参数不满足能量守恒定理。因此,定义S参数前向、后向损耗因子,直观反映测量系统的能量损耗分布情况。同时,通过构建频域测量系统方程,采用Kalman数据估计方法有效地降低了损耗因子,提高了数据测量精度。
[Abstract]:In the process of two-port microwave network measurement, random error is one of the main factors causing measurement error, and the S parameter does not satisfy the energy conservation theorem. Therefore, the forward and backward loss factors of S parameters are defined to reflect the energy loss distribution of the measurement system intuitively. At the same time, by constructing the frequency domain measurement system equation, the Kalman data estimation method is used to effectively reduce the loss factor and improve the accuracy of data measurement.
