3DSS-iDX
Integrated Shallow Water Mapping/Imaging System
The 3DSS-iDX utilizes state-of-the-art acoustic transducer array technologies, SoftSonar(TM) electronics, and advanced signal processing techniques to produce superior swath bathymetry and 3D side-scan imagery in a compact survey package. The 3DSS-iDX is a complete hydrographic/3D imaging sonar and INS for portable, turnkey, survey applications.
Description
3DSS-iDX incorporates a patented signal processing methodology that extends the single angle-of-arrival principle used in interferometric systems to accommodate multiple simultaneous backscatter arrivals (e.g. the seabed, sea surface, water-column, and multipath). The result is superior wide swath bathymetry and true 3D sidescan imaging and from a compact, easy-to-use sonar.
The iDX-450 integrates SVT and MRU sensors into the sonar head and a dual receiver GNSS into the advanced Sonar Interface Unit (SIU) to form a turnkey Sonar/INS system for high accuracy shallow water surveying. The 3DSS-iDX sonar can be used standalone or together with an external MRU, GNSS or INS sensor on a fully equipped survey launch or USV / ASV.
