The current work is involved in the application of specially designed multibeam sonar (SM2000) to fishery researches. Unlike the traditional sonar that is designed to gate out the mid-water signals, this one allows us to capture both the mid-water and the bottom returns. The broad water column coverage will give us much information for accurate data analysis. Meanwhile the large data resulted from the survey requires prompt processing. One goal of the research is to find a way to correctly interpret the signal data in term of bio-mass; and another one is to develop highly efficient software tools to do real-time 3D visualization and signal analysis.
