The Development of an Ultrasonic Measuring System for the Tracking of a Moving Target : 1st Report, Methodology and Theory : Vibration, Control Engineering, Engineering for Industry

Abstract

A system using ultrasonic sensors was developed to track a moving target. In Part 1, a new technique for sharpening the ultrasonic beam, and for attaining a higher accuracy in the determination of the direction of a moving target was proposed. Furthermore, a new electronic technique for sweeping the emitted beam, for searching more rapidly a moving target in space, was proposed. In Part 2, an outline of the system and its experimental performance are described.
