  • Real-time calibration acoustic array
    Patent number: 5530678
    Abstract: A method and apparatus for acoustic array calibration. A housing with an opening on one side contains the acoustic transducer element. An acoustically transparent window covers the opening in the housing. A separate piece of substantially acoustically transparent planar transducer film is positioned in front of each transducer element. This film monitors the acoustic energy transmitted by the transducer elements, or alternatively transmits energy to the transducer elements. The transducer film can also operate as an independent hydrophone.A method for calibrating acoustic arrays is also disclosed. The transducer film monitors the acoustic energy transmitted by each acoustic transducer. The level of transmitted acoustic energy is independently measured by external calibration equipment. The acoustic energy received by each transducer film is compared with that measured by the external equipment to determine a calibration factor for each transducer element.

  • Volumetric and terrain imaging sonar
    Patent number: 5200931
    Abstract: A method and apparatus for the generation of a three-dimensional image representing structures detected within a volume. Two dimensional differential phase measurements are made on backscatter signals. Azimuth, elevation and range are calculated over a statistically large number of spatially diverse backscatter returns and used to construct a histogram of backscatter data. The histogram of backscatter data can be processed with standard image processing techniques to produce terrain maps or volumetric models of the volume of water. A system constructed according to the methods of this invention is capable of producing a three-dimensional map of the volume insonified without mechanical array scanning or electronic beam scanning. A combination of two or more volumetric scanning systems can be used to increase the resolution achievable in modelling the volumetric area.
