Abstract:

An experiment was performed in a small laboratory tank to study the feasibility of modeling an active sonar in a shallow water environment. The modeling frequency of 1000 kHz in a two meter tank indicated fair compatibility with theory for the short scaled ranges studied. An initial spherical spreading loss followed by a cylindrical spreading loss, bottom loss effects, and Lloyd mirror interference were observed. The methods were observed. The methods were suitable for future modeling experiments. Author
