Abstract
This paper describes of new approach to Multifrequency Wideband Arrays (MWA),applied piezocomposite technologies of the array elements. MWA operating in transmitting(Tx) and receiving (Rx) mode on two or three bands, requires state-of-the-art technology andefficient array designing than conventional array in which separate arrays for every band oreven separate Tx and Rx transducers/arrays are used. The new piezocomposite elements aredesigned at OBR Centrum Techniki Morskiej S.A., manufactured by Materials Systems Inc.(Littleton, USA) and tested at the cooperation with Gdansk University of Technology.The article presents research and development work at the multifrequency widebandpiezocomposite arrays elements. An example of dual frequency wideband Tx/Rx array withdesign parameters and its implementation for the dual frequency wideband sonar will bepresented. The results of array elements measurements: TVR, RVS, Impedance and Phaseversus frequency from 50 kHz to 500 kHz as well as beam patterns, will be also presented.
