 The study is concerned with probe methods of displacement measurement. The aim of this stage is to develop a method for phase ambiguity resolution in three-probe mechanical displacement measurements with account for the horn antenna reflection coefficient. Method: analytical calculation and computer simulation. An equation relating the unknown reflection coefficient magnitude of the object under measurement to the semiconductor detector currents is obtained with account for the horn antenna reflection coefficient. A sufficient condition is found for the object reflection coefficient magnitude to be its smaller positive root. A phase ambiguity resolution method is developed to unambiguously determine the object displacement from the semiconductor detector currents with account for the horn antenna reflection coefficient. The results may be used as informational and methodological support at the next research stages.
