The Original Side Scan Sonar (Shallow Water).
The full-body, three-fin, hydrodynamic design of the StarFish systems challenge the common cylindrical or torpedo-shape of traditional side scan sonars. The unique shape of the StarFish systems dramatically improves the stability of the sonar and consequently the quality of the images it produces. Advanced digital CHIRP (Compressed High Intensity Radar Pulse) acoustic techniques used by StarFish systems offer better range resolution compared to conventional, fixed-frequency side scan sonars.
The StarFish 450F is the original StarFish Seabed Imaging System and continues to offer a powerful, yet affordable, entry-level side scan sonar system for shallow water survey work. The system is powered by a 450kHz CHIRP transmission, to provide a wide range sonar coverage up to 100m/ 300ft per channel (200m/ 600ft total swathe) with good, clear image definition. This model is also available as a hull-mounted version (StarFish 450H).
