This system can be categorized as an enhanced sidescan system that delivers geo-referenced backscatter samples, with multiple transducer groups per head, phase detection and advanced data processing.
An angle can be obtained per sample.

The sonar system broadcasts UDP packets to port 5001 over the network to this driver. 
The packets contain:

  • raw angle
  • amplitude
  • travel time per sample
  • quality flag
