Abstract
Example sonar transducer assemblies configured for reduced interference are provided herein. An example sonar transducer assembly includes a housing, a first transducer, and a second transducer. The first transducer is positioned within the housing such that a length is configured to extend in a first mounting plane and a produced first beam defining a fan-shape extends in a first plane. The second transducer is positioned at a tilted angle within the housing such that a length is configured to extend in a second mounting plane and a produced second beam defining a fan-shape is in a second plane. The second mounting plane is non-parallel to the first mounting plane and is offset from the first mounting plane by at least 1 degree such that the second plane is not parallel to the first plane so as to reduce interference between the first transducer and the second transducer.
