Dense Transducer Array

A dense transducer array is an acoustic transducer with relatively high operational bandwidth. It includes a cable harness component that provides and organizes various conductors within piezocomposite substrates to form transducer arrays with minimum impact on electroacoustic performance. Several underwater sonar applications exist for high-frequency wideband transducer arrays having individual elements. In order to form and steer acoustic beams with an array of individual elements, the array elements must be spaced not more than one-half the acoustic wavelength at the highest frequency of interest. This implies, for square-shaped elements at least, that the elements' lateral dimensions are inversely proportional to frequency. Therefore, for fully populated radiating apertures, the number of elements increases exponentially as the spacing decreases.
