Designing ocean acoustic waveguide remote sensing for target detecting and tracking

Abstract

Acoustic sensor used sound wave to transmit pulses into the underwater in order to gain underwater environment information. We developed Ocean Acoustics Waveguide Remote Sensing (OAWRS) instrument. The acoustic signal acquisition system has been designed which used to record the direct, reflected, scattered or echoed signals originated from transmitter transducer, targets or underwater objects. The acquisition system compose of interconnected hardware and software with a simple working principles. The software, which is written under Windows™ and Matlab, controlled the hardware by sending commands to the Transmitter Module located somewhere to generate a sound pulse and the Receiver Module to be ready to receive sound signals. The received sound data may be recorded for further analysis to developed OAWRS algorithm.
