I belong to an AUV team at my university. We are planning to have a Multibeam 2D Imaging Sonar (the Blueview P900) for our AUV to detect obstacles underwater.
I have the following questions to ask on the feasibility of testing/implementing such sonars on AUVs.
As we know that these multibeam sonars have multiple reflections arriving at different times from various surfaces while testing in a pool, is there any recommended way to filter these noises in the image obtained from the sonar pings?
Are such sonars in use/test by any other team/organization anywhere else who do pool testing other than a ocean/reservoir testing where multiple reflections are almost zero except the reflections from the obstacle(s)?
Also i would like to know the recommended image processing algorithms that can be implemented/used to detect obstacles from the sonar images.
