||The 2205 Series is a flexible and configurable sonar system with applications for use on autonomous and remotely operated underwater platforms (e.g. UUVs, ROVs, AUVs, and USVs). The instrument comprises a modular unit which can be configured based on the application, to collect side scan sonar images, sub-bottom profiles and bathymetric data either singularly or simultaneously. The 2205 Series can operate independent of the underwater platform by recording and storing the data or be integrated into the vehicle. The instrument also features nadir gap-fill sonar, full spectrum CHIRP processing, multi-pulse technology, dynamically focused arrays, and dynamic aperture sonar arrays. Applications of the 2205 Series include archaeological, geophysical, cable and pipeline, dredging, and marine construction surveys, benthic habitat mapping, and marine debris search operations. The side scan sonar is capable of operating at seven frequencies between 75 and 1600 kHz depending on the depth application (from 35 to 1000 metres to target) and can be configured to operate in dual or tri-frequency modes. Depth ratings include to 3000 or 6000 metres. The sub-bottom profiler has three frequency ranges: 4 - 24, 2 - 16 and 1 - 10 kHz, with vertical resolutions of 4 - 8, 6 - 10 and 15 - 25 cm respectively.
