Patent number: 11531083Abstract: Techniques are disclosed for systems and methods to provide a staggered multichannel transducer in a ranging system configured to perform remote sensing. The staggered multichannel transducer may extend in a first direction and one or more transducer elements of the array may offset from the other transducer elements in a second direction perpendicular to the first direction.

Patent number: 11408985Abstract: Techniques are disclosed for systems and methods to provide accurate and reliable compact sonar systems for mobile structures. A sonar system includes multiple sensor channels, each comprising a sonar transmitter and a sonar receiver, and a logic device configured to provide control signals and receive sensor signals from the sensor channels. The logic device is configured to provide transmission signals to sonar transducer assemblies, where signal patterns of the transmission signals are differentiated based at least in part on frequency content. Acoustic returns are processed using the signal patterns to reduce inter-channel pickup between the sensor channels. Resulting sonar data and/or imagery may be displayed to a user and/or used to adjust a steering actuator, a propulsion system thrust, and/or other operational systems of the mobile structure.Type: GrantFiled: June 28, 2019Date of Patent: August 9, 2022Assignee: Teledyne FLIR, LLCInventors: Paul Stokes, William Sayer, Paul Muller, David Wellcome, Gordon Pope
