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.
期刊介绍：
Instruments and Experimental Techniques is an international peer reviewed journal that publishes reviews describing advanced methods for physical measurements and techniques and original articles that present techniques for physical measurements, principles of operation, design, methods of application, and analysis of the operation of physical instruments used in all fields of experimental physics and when conducting measurements using physical methods and instruments in astronomy, natural sciences, chemistry, biology, medicine, and ecology.
