DETECTION OF RIVERINE FISH USING AN ADAPTIVE EIGEN FILTER DIRECTIONAL SPECTRAL ESTIMATION TECHNIQUE
P. BRADY et M. YAMINYSHARIFDepartment Electrical and Electronic Engineering, Napier Polytechnic, Edinburgh, Great-Britain
Abstract
The advent of fast cheap microprocessor devices has meant that digital signal processing may be the most realistic technique to provide a method of detecting the amount of fish that are ascending and descending a river. This information is invaluable to the fisheries manager. The paper describes a technique which could be the basis of a system which would afford us all the data necessary to design a practical system for use in Scottish rivers. A simulation of the technique has been carried out to determine feasibility.
