Abstract:

The development of metrics for the comparison of data obtained from measured synthetic aperture sonar SAS data or from numerical models is investigated. Metrics are needed for quantitative comparisons for signals obtained from either different models, the same model with omitted physics, controlled experiments, or actual operational MCM systems. Specifically, candidate metrics for model-model comparisons are examined here with a goal to consider raw data prior to its reduction to data products, which may be suitable for input to classification schemes. The investigated metrics are then applied to model-data comparisons.
