Digital sidescan sonars are functionally identical to analog sonars, i.e. they ping (transmit) and listen for echoes, which are recorded as backscatter from the seabed. Images are built up by recording sequential pings. The chief distinguishing factor of digital sidescans is that they output digital data, as opposed to analog voltage signals. True digital systems digitize the sidescan data in the towfish, so that the data can be transmitted noise-free over longer cables than would be possible with analog sidescans.
Interfaces for digital systems are usually serial (USB or RS-232/485), Parallel, High-speed serial (SDLC), or Ethernet, the latter being most common in high-resolution systems. GeoDAS provides specialized interfaced for each system.
