Long-range target detection and classification system for environmental monitoring at marine hydrokinetic (MHK) sites

Abstract

BioSonics and team members are developing a practical, unobtrusive, robust, and cost-effective long range (200–300 m) active acoustic monitoring system to automatically assess marine life behavior at potential or operational MHK sites. The proposed system includes a Perimeter Detector, that will automatically detect and geolocate targets at ranges of 200–300 m. The system will include a Directed Classifier that will be automatically aimed at a detected target to track the target’s position in three dimensions. This tracking capability allows automated measurement of the target’s behavior (i.e., speed, direction, and tortuosity), a strong indicator of target classification. Acoustic signatures from tracked targets will be analyzed to provide additional target classification information. Low band width, real-time reports will be automatically generated and transmitted to project operators, including target location, depth, behavior, and classification.
