Paper Abstract

Representative data pertaining to various critical aspects of air-coupled ultrasonic Doppler sensing of ground vibrations are presented. The behavior of an ultrasonic sensor is systematically compared with that of commercial laser vibrometers. The inherent drawbacks and advantages of both techniques are discussed and evaluated in systematic experiments. The experiments are designed so as to synthesize various scenarios that may be encountered in practice. Thus the vibration sensing capability of ultrasonic vibrometers is investigated in cases including flat and grass-covered surfaces, granular media, with and without ambient air motion. The work is supported by the Office of Naval Research.
