We use Kirchhoff-ray mode (KRM) models to investigate acoustic backscatter from individual and aggregations of aquatic organisms. Backscatter models can be used to calculate echo amplitudes for individuals or groups with known size distributions. We compare model predictions to measurements in the laboratory, in the field (actually in the water), and are finding new uses for backscatter models all the time. Here are results from recent projects:
