Development of the parametric sub-bottom profiler for autonomous underwater vehicles - Prediction of the reflection level using sonar equation based on TBE and Biot-Stoll model

The exploration of buried deposits under the sea sediment requires high directivity and low attenuation beams. The parametric sub-bottom profiler (PSBP) meets these requirements; moreover, it is comparatively small and can be easily mounted on autonomous underwater vehicles (AUVs). For this reason,...

Summary:The exploration of buried deposits under the sea sediment requires high directivity and low attenuation beams. The parametric sub-bottom profiler (PSBP) meets these requirements; moreover, it is comparatively small and can be easily mounted on autonomous underwater vehicles (AUVs). For this reason, we are developing a new PSBP system for AUVs. In this study, the performance of the PSBP system is estimated by using a sonar equation based on the transformed beam equation (TBE) and the Biot-Stoll model to optimize the measurement system.
