In this paper three case studies of the application of a compact non-contact, non-destructive setup are presented. The herein employed method is based on the air-coupled detection of acoustic waves in the frequency range up to 2 MHz.

Different approaches for determining the position of the reflection point of a transmitted ultrasound signal are investigated assuming a specular environment. Two different principles are outlined: one based on the evaluation of time of flight (TOF)

A main aspect in wireless sensor networks (WSN) with numerous sensor nodes is location awareness. While major scientific activities are concentrated to ultra-wideband solutions, some systems specially designed for indoor application try to rely on ul

With the final goal of three dimensional scene analysis by ultrasound echolocation, two approaches are discussed for determining the position of reflection points on specular objects. The first approach uses time-of-flight information at four receive

In this paper correlation techniques are discussed to extend the measurement range of an ultrasonic transducer to its side lobes. Broadband coded signals (linear chirps) are used to steer the transducerpsilas radiation pattern. The presented method a
