FIELD: measurement technology, measurement of linear velocities of bodies traveling in space-outer space, airspace, expanse of water. SUBSTANCE: method makes it feasible to determine linear velocity of travel of body hen there is no information communication of this body with any other bodies. Trains of coherent electromagnetic waves are directed in opposition along one straight line in vacuum for the course of limited time. During time that does not exceed radiation time number of nodal points or crests of standing wave in vacuum is counted and desired velocity is computed by their number and length of electromagnetic wave. EFFECT: enhanced authenticity of method. 1 dwg
