EdgeTech, a leader in high resolution sonar imaging systems and underwater technology, continues to make great strides with the ever growing field of smaller sized AUV systems around the world. With the introduction of the 2205 AUV-based sonar system, manufacturers and operators of smaller sized AUV systems have embraced the high quality sonars which were traditionally only available in larger sized AUV systems. One area that continues to see an adoption of the smaller size vehicles is the military community. High performance compact sonar systems have helped that growth curve.
The recently delivered Teledyne Gavia AUV’s to the Polish Ministry of Defence for mine countermeasure’s (MCM) were equipped with the latest EdgeTech 600/1600 kHz simultaneous dual frequency side scan sonar payloads. The very high frequency EdgeTech systems were selected for the long range detection and the ultrahigh resolution classification capability for MLO’s (mine like objects). The EdgeTech 2205 classification frequency of 1600 kHz is capable of producing near photographic quality images of targets making MLO target classification very easy as shown in the attached MLO sonar image. Other 2205 attributes that contributed to the selection of the EdgeTech systems were low power, small electronics’ volume and compact transducers making integration on the small AUV’s possible and easy.
EdgeTech sonar systems have now been installed on a number of manned portable autonomous underwater vehicles used in Navy operations and commercial surveys. System configurations include a range of side scan sonar frequency offerings such as 400/900 kHz frequency pairs or 600/1600 kHz frequencies which are unmatched in the high resolution capabilities. Additionally the system can be configured to provide bathymetry on top of the dual frequency side scan sonar solution
