Abstract
In this paper, we describe a method for restoring reflector motion using a radio-wave signal from a super high frequency (SHF) autodyne generator based on a Gunn diode. The proposed method consists in sequential emission and reception of an electromagnetic SHF signal reflected from an object using two channels that differ in electrical length providing the π/2-phase shift of interference signals. With this method, there is no ambiguity in determining the amplitude of reflector movement and no need to determine the initial phase of the detected signal.
