    Abstract: Techniques are disclosed for systems and methods to provide high resolution interpolation of arrival direction of echo return signals using an active mills cross arrangement, such as in sonar or other ranging sensor systems. A system may include an active mills cross arrangement with high resolution interpolation of echo returns in two planes. The active mills cross arrangement may include a transmitter configured to emit one or more signals, a first line array including a first plurality of elements defining a first plane, and a second line array including a second plurality of elements defining a second plane orthogonal to the first plane. At least one of the first line array and the second line array may be configured to receive echo returns of the emitted signals from one or more objects or targets.

    Abstract: Techniques are disclosed for systems and methods to provide sonar systems for mobile structures. A sonar system includes a sonar transducer assembly including a sonar transducer, a sonar receiver configured to receive acoustic returns from the sonar transducer and convert the acoustic returns into arrays of time differentiated sonar data samples, and a logic device adapted to communicate with the sonar receiver. The logic device is configured to receive the arrays of the time differentiated sonar data samples from the sonar receiver and process the received arrays to enhance the time differentiated sonar data samples substantially without enhancing sonar artifacts in the time differentiated sonar data samples Processed sonar data and/or resulting 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 sonar transducer assembly and/or a mobile structure.

    Abstract: 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.

    Abstract: Techniques are disclosed for systems and methods to provide accurate and compact three dimensional (3D) capable multichannel sonar systems for mobile structures. A 3D capable multichannel sonar system includes a multichannel transducer and associated processing and control electronics and optionally orientation and/or position sensors disposed substantially within the housing of a sonar transducer assembly. The multichannel transducer includes multiple transmission and/or receive channels/transducer elements. The transducer assembly is configured to support and protect the multichannel transducer and associated electronics and sensors, to physically and/or adjustably couple to a mobile structure, and/or to provide a simplified interface to other systems coupled to the mobile structure. 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.

    Abstract: A wideband sonar receiver is provided that includes: a selectable bandpass filter adapted to filter a received sonar signal to produce a filtered signal and a correlator adapted to correlate the baseband samples with baseband replica samples to provide a correlated signal. In addition, the wideband sonar receiver may include a shaping filter to shape unshaped received pulses. Finally, a variety of sonar processing algorithms are described with regard to reducing clutter and interference, target detection, and bottom detection.
