Position, velocity profile measurement of a moving body by microwave interferometry

A telemetric sensor that uses microwave interferometry to determine the velocity profile of a moving body following a known linear trajectory is proposed. By a slight modification of the design, it is possible to determine both the velocity profile and the distance to the trajectory. The principle of the method and the preliminary experiments carried out in the laboratory before extending the process to full-sized outdoor applications are described. The experimental results confirm the feasibility of the concept. >
