Sidescan Sonar Surveys

The Starfish range has gained worldwide recognition as the most compact, affordable, towed side scan sonars for the professional underwater survey industry. 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. Furthermore, the 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. StarFish 990F is the ultimate high-resolution side scan sonar for extreme image definition and target detection. The sonar uses a high frequency 1MHz CHIRP transmission with extremely narrow horizontal acoustic beam to provide the sharpest, most defined images. With 150 m range capability on each channel (334m total swathe coverage), the sonar is ideal for high-resolution survey in ports & harbours, inland waterways such as rivers and canals and excels when used for SAR (Search and Recovery/Rescue) operations.
