An understanding of algorithmic and engineering techniques for the construction of a high-quality microphone array system for speech input to machines is the goal of this project; it implicitly assumes that wearing a head-mounted microphone, or sitting at a fixed location in front of a table microphone is most often an unacceptable imposition for a user of a speech recognizer. Rather, the array...

The receiver hydrophone array is the signal front-end and plays an important role in matched field processing, which usually covers the whole water column from the sea surface to the bottom. Such a large aperture array is very difficult to realize. To solve this problem, an approach called matched field processing based on least squares with a small aperture hydrophone array is proposed, which ...
