Abstract
This paper describes a wideband acoustic source made of piezoelectric polymer (PVDF) material. The source was developed for the characterization and absolute calibration of ultrasonic hydrophone probes. Construction details are described and performance characteristics of the wideband PVDF transmitter, including its transmitting voltage response and directivity patterns, are presented in the frequency range up to 40 MHz. The KLM model was used to examine the influence of the PVDF polymer film thickness, the backing acoustic impedance, the cable length, and the electrical source resistance on overall transmit transfer characteristics
