Design & Development of a Shallow Water Echo-Sounder for Marine Platforms

EasyChair Preprint 15456

Abstract

— Underwater echo-sounders form an integral part of sonar suite for both surface and sub-surface vessels. These systems ensure the safe operations of the fleet by providing real time distance between boat keel and sea bottom. Herein we report the design and development of a shallow water echo-sounder with excellent acoustic parameters for fleet vessels. Peak Transmit voltage response (TVR) of 170 dB, receive voltage sensitivity (RVS) of –187 dBV/µPa and Electrical impedance of 193 Ω were measured for the prototype echo-sounder. This design revealed a 10 dB gain in acoustic tests with reference to conventional oil filled designs. Furthermore, the design of this acoustic transducer has the flexibility of tuning the frequency by controlling the sensor geometry. This flexibility ensures the control over operational frequencies and customization as per requirement.
