US Patent:

20120106299, May 3, 2012

Filed:

Oct 26, 2011

Appl. No.:

13/282257

Inventors:

Francis Dale Rowe - Poway CA, US
John Romeo - San Marcos CA, US

International Classification:

H04B 1/02

US Classification:

367138

Abstract:

Improved two-dimensional planar array transducer and beamformer apparatus and methods. In one embodiment, the two-dimensional planar array transducer is capable of simultaneously or sequentially forming multiple acoustic beams in two axes and at two or more widely separated acoustic frequencies from a single flat planar array transducer. The transducer planar array consists of two or more electrically and acoustically independent two dimensional planar transducer array structures operating at different frequencies that are physically integrated onto a single multi frequency configuration. In an exemplary embodiment, a second higher frequency transducer array is positioned within the aperture area of a lower frequency planar array transducer. Methods of using the aforementioned two-dimensional planar array transducer and beamformer are also disclosed.
