EdgeTech’s 4600 is a combined, fully integrated, swath bathymetry and side scan sonar system. The 4600 produces real-time high resolution three dimensional (3D) maps of the seafloor while providing co-registered simultaneous side scan and bathymetric data.
The 4600 uses eight receive element transducers and one discrete transmit element. The high number of channels enables superior rejection of multi-path effects, reverberation and acoustic noise.
Utilizing EdgeTech’s Full Spectrum® technology, the 4600 meets the IHO SP-44, NOAA and USACE specifications for feature detection. The Full Spectrum Technology® processing techniques also provide a denser data set in the nadir region compared to other interferometric systems. Near shore and shallow water hydrographic surveys are completed faster and safer utilizing the 4600 due to the wide swath, which is typically more than two times that of existing sonars that rely solely on beam forming techniques.
The sonar electronics and arrays for the 4600 are mounted onto a streamlined tow body that is deployed over the bow or over the side of the survey vessel via a pole. Alternatively, the sonar can be used as a towed system or configured for AUV, UUV or ROV operations. Sonar data is transferred from the transceiver to the processing unit on board via an Ethernet network interface.
The standard configuration for the 4600 includes an integrated sound velocity sensor and interfaces with standard GPS, MRU, SVP, CTD, Altimeters and Gyros. The 4600 interfaces to most 3rd party acquisition and processing software as well.
