A coustical contribution to automatic identification of moving objects

Abstract

This paper sets out an automatic identification system-based on an acoustic principle-with regard to animals . The animal carries a resonant object which produces a sound when it moves . Thus, the animal is identified by the emitted sound. First a probability then frequential model leads to an algorithm of identification involving a system eliminating interférence . Front these results, we have developped a prototype which permits the testing of the efficiency on the spot . Finally, we have tested the reliability of this new type of identificator .Description d'un dispositif d'identification automatique d'animaux fondé sur un principe acoustiqu
