Marine Electronics Sand Ripple Imaging Sonar The Sand Ripple Imaging (SRI) Sonar provides high resolution images in a transportable PC format for the minimum cost. Typically the sonar would be mounted near to the seabed and used to scan a circular area of the seabed up to 5m in range. The SRI Sonar operates at 2MHz with a 1 horizontal beamwidth and a 30 vertical beamwidth. Alternative transducers may be fitted to givedifferent beam patterns and ranges depending on the specific application. In use the SRI Sonar requires a serial connection to a PC which controls the scanning process.The analogue output from the sonar provides freedom inthe users choice of external signal processing. The transducer is fully enclosed in an oil filled rubber "boot" with no external rotating parts for complete environmental protection. |
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. |
