Sand Ripple Profiling Specifications

Marine Electronics Sand Ripple Profiling Sonar

The Sand Ripple Profiling (SRP) Sonar effectively operates as an imaging sonar as it digitises the amplitude of the returned echoes over a programmed range. This approach allows the user to post-process the data to remove noise and mid-water targets caused by sand particles or fish. The SRP Sonar operates at 2MHz with a 1.1 conical beam to give precise range and bearing information over the scanned area which may be up to 360. Typically the SRP Sonar is mounted horizontally near to the seabed and scans a cross-section of the seabed over an angular range of 120. A data logging version is available with a built in hard disk for remote data gathering.The transducer is enclosed in a PVC "boot" with no external moving parts for complete environmental protection.
