Abstract

We propose the development of a compact broadband underwater cylindrical transducers with integrated tuning networks and power amplifiers for Mobile Acoustic Counter Measures. There is a need for cost effective transducers that are broadband and have broad-beam coverage. BTech has designed and built improved counter measure transducers as well as acoustic modem transducers using both PZT materials as well as designs using segmented single crystal (PMN-PT) rings, which offer increased bandwidth and electroacoustic efficiency. Our innovative PZT and single crystal transducer technology, combined with state-of-the-art power amplifier designs, will provide cost effective compact broadband solutions.
