Abstract

The results of a study of three methods for determining the phase of signals from a heterodyne microwave interferometer are presented: phase calculation by processing digitized signals using software methods; direct phase measurement with an AD8302 detector; and phase measurements by quadrature detection. The results of phase measurements obtained by these methods are compared. The values of errors of each method are estimated and ways to minimize them are considered.

以 PN-3 微波干涉仪为例比较相位提取方法

摘要介绍了确定外差微波干涉仪信号相位的三种方法的研究结果：使用软件方法处理数字化信号进行相位计算；使用 AD8302 检测器直接测量相位；以及通过正交检测测量相位。比较了这些方法获得的相位测量结果。对每种方法的误差值进行了估算，并考虑了将误差最小化的方法。
