Technological evaluation of a fresh water bathymetry system

We present the progress made in the development of an instrumentation system for fresh water bathymetry. Several design considerations are analyzed, such as transducer element characterization, SONAR equation modelling, and conceptual design of the instrumentation electronics. A Class-D, “Half-Bridge” configuration is proposed to drive the transducer used for transmission and reception. General system modules are also introduced. Future work involves the construction of a prototype based on this design to evaluate its performance.
