The evolution of new concepts inwave theory have led to proof-in-principle experiments aimed at validating the generation of a specified wave front. Not only have these concepts initiated research in transient wave theory, but they have also caused renewed effort in multichannel signal processing. In this paper, the development ofa processor todeconvolve a transient acoustic wave from sensor ar...

Surface acoustic devices have been shown to be suitable not only for signal processing but also for sensor applications. In this paper high t h t b O ©

one of the most common signals used for achieving high range resolution in radar is stepped-frequency signals. when a target is stationary in these radars, dft (discrete fourier transform) based processing is used to attain high range resolution profile (hrrp). however, in the case of moving target, due to spreading of the echo signal spectrum, dft based processing is not optimal and decreases ...

In my opening remarks the acoustics and signal processing involved in active control will be reviewed: both for enhancing audio signals and for attenuating acoustic noise. The physical limits due to the geometry of practical arrays will be discussed, together with the signal processing design methods that can be used to implement robust practical arrays, whose performance approaches these geome...

Although traditional signal-based structural health monitoring algorithms have been successfully employed for small structures, their application for large and complex bridges has been challenging due to non-stationary signal characteristics with a high level of noise. In this paper, a promising damage detection algorithm is proposed by incorporation of adaptive signal processing and Artificial...

A scheme for binaural pre-processing of speech signals for input to a standard linear hearing aid has been proposed. The system is based on that of Toner & Campbell [1] who applied the Least Mean Squares (LMS) algorithm in sub-bands to speech signals from various acoustic environments and signal to noise ratios (SNR). The processing scheme attempts to take advantage of the multiple inputs to pe...
