Naval Technology: ECA Group presents new mid-size AUV A18-M underwater vehicle
The AUV A18-M can carry out effective mine detection and classification in all water depths up to 300m.
The unmanned vehicle has been specifically developed to operate in close vicinity to the most advanced mines without triggering them.
"With the only possible exception of buried or concealed mines, all known mines can be detected and high-quality classification cues can be extracted."
ECA Group AUVs product manager Léonie Delacou said: “This mid-size AUV is the top trade-off between, size, weight and long endurance.
“Its payload capacity makes it able to host high-performance sonar such as synthetic aperture sonar (SAS), providing unprecedented detection and classification performances.”
The compact design of the AUV A18-M enables easy deployment from small naval platforms such as the latest unmanned surface vehicle.
In addition, its enhanced stability also allows it to deliver high-quality images and sonar image’s raw data to be processed in real-time.
A list of contacts is extracted and relayed back to the command centre via an advanced communication network, using an USV or unmanned aerial vehicle as the gateway to be analyzed either on-board a mothership or onshore, in order to launch identification and disposal.
Furthermore, the drone can detect any kind of hazard such as improvised explosive devices (IEDs) and pollutants, as well as provide precise maps of the seabed.
ECA Group Systems of Robots programme director Dr Marc Pinto said: “The performance gain is due to the very-high resolution in both range and cross-range offered by a wideband SAS of the order of 2.5cm x 3cm constant up to the edges of the swath, which is unachievable at any practical range by any other type of sonar on any type of platform.
“With the only possible exception of buried or concealed mines, all known mines can be detected and high-quality classification cues can be extracted from the highlight and shadow structure.”
