Fans of individually transmitted and received beams can be used either for bathymetry with a wider swathe or for detection of embedded targets via generated low frequencies.

In common with other models, the system can also be supported by electronic beam steering and stabilisation using an industry standard motion sensor. Storage of data is digital for extended post-processing of findings.

Innomar says the first Fan system has already been commissioned by Hamburg’s University of Applied Sciences who plan to use it for various research projects as well as education of hydrographic and geomatics students.
