(Some of the) Basic Research Activities at ADS Islam I. Hussein ihussein@applieddefense. com December 8 2016

Information Theory for SSA • Probabilistic Admissible Region (PAR) – Used for observation-based object birth handling – Single optical observation – Future Research: • Transitioning to operations • Short-Arc Optical Uncertain Track Initiation

Information Theory for SSA • Information-based Data Association – Track-to-Track Association; Observation-to. Observation Association – Employing information divergence, information entropy and mutual information concepts – Pursuing particle MC and Gaussian/ GMM approaches • Future Research Directions – Photometric Data

Multi-Sensor, Multi-Target DTIC and Information-based Sensor Tasking • Multi-sensor, multi-target joint tracking and characterization (observation -> cataloging) – Large scale computational complexity reduction – Indications and warnings (hierarchical reasoning + FISST) • RFS-based information gain metric for multi-sensor tasking for: – Finite horizon catalog maintenance – Finite horizon event response • Future research directions – Sensor and modality selection

Directional Data Analysis for SSA (EOARD Funded) • Joint work with Prof. John Kent at Leeds University and Dr. Moriba Jah at Uof. A • Employing statistical data analysis for SSA – Fisher-Bingham-Kent Probability Density Function to • Represent track uncertainty as observed by optical sensors • Modify classical UKF implementation to account for optical data • Achieve higher fidelity data association for anglesonly directional data • Future Research Directions – Incorporation into the RFS-based framework
