Research Project Objectives • Develop overall algorithm for detection of: Tanks under trees; landmines • Initial focus:TUT (can hit the ground running) • Features of algorithm: sequential detection, sensor management & selection, physics-based models • Simplify stochastic physics-based models using: functional-analysis-based approximation • Evaluate the resulting procedure on realistic models (statistical simulations) and real data
Issues: Overall Algorithm • How to select sensing modalities? • What is value-added for combining other modalities? Is it worth additional cost? • How do we implement data-adaptive configu-rations, e.g., selection of sources/receivers, based on scattering of targets and propagation in medium? • What are the figures of merit? • How to select decision thresholds?
Physics based models
Summary • Sequential detection and classification • Sensor scheduling and management • Physics-based models with dimensionality reduced using functional analysis • Vehicle and canopy scattering models already at UM permit test evaluations
