Edgetech: New Sonar

Frequency Combo

EdgeTech introduced a new sonar fre- quency combination suited for shallow water

USVs and UUVs. The new 850kHz and 1600kHz dual frequency combination pro- vides high resolution side scan sonar imagery at both frequencies and optional bathymetry at 850kHz. The new frequency pair is avail- able in EdgeTech’s 2205 hosted platform product line of solutions. The EdgeTech 2205 is a compact, extremely ? exible and con- ? gurable sonar system for integration on 3rd party underwater and surface vehicles. This modular unit can be con? gured, based on the

New LR Acoustic Effector customers’ application, to collect side scan

GeoSpectrum Technologies, an Elbit Systems’ subsidiary, introduced sonar imagery, sub-bottom pro? les and bathy- the C-Bass family of compact Very Low Frequency (VLF) long-range metric data, singly or in concert with one acoustic underwater transducers. The GeoSpectrum patented C-BASS another. The system is provided as a com- family of underwater transducers offers a deployable system that is plete package where the 2205 electronics are small in size and weight but still maintains the high-power and frequen- enclosed in a pressure vessel, or alternatively cy range (bandwidth) of legacy systems. Designed to be robust, afford- the core electronics can be provided as boards able and easy to operate with, ranges exceeding 2500 km and capable to mounted onto a chassis so the customer can effectively operate under ice, the C-BASS family of transducers is suit- integrate the system into their vehicle’s dry able for a wide range of sub-sea applications including: communication/ electronics area. transmission from shore or surface units to submarines; divers’ alert and www.edgetech.com communications; communication with Unmanned Underwater Vehicle (UUV) for control/positioning; mine sweeping, as well as augmentation of submarine signatures when transiting in or out of ports or narrow passages. C-BASS transducers are available in a variety of sizes and con? gurations from the 20 cm diameter con? guration that can even ? t in a medium UUV up to the 1.1 m diameter unit used in a multi-source high-power con? guration for seismic exploration.

Ultra High Resolution Imaging Sonar

Blueprint have recently extended its sonar product range with the introduction of the

M3000d dual frequency multibeam imaging sonar. For general purpose navigation and target detection the sonar is operated at 1.2MHz. This provides a maximum range capa- bility of 30m and an acoustic aperture of 20 by 130 degrees. While the image quality at this frequency is impressive, it may be further improved by switching the sonar to 3MHz for target identi? cation. At this frequency the sonar provides an exceptional acoustic angular resolution of 0.25 degrees and a beam spacing of better than 0.1 de- grees. Near ? eld focusing is performed digitally within the sonar and offers a minimum range capability of better than 10cm. All of this is done using the standard Oculus form factor, with a small space envelope and a weight in water of under 400g making it an ideal solution for small ROVs and diver handheld systems.
