Cramer-Rao Lower Bound Derivation and Performance Analysis for Space-Based SAR SMTI
… target signal model is derived in satellite earth-fixed earth-centered coordinate system. This model is used in space-time adaptive processing (STAP) approaches for SMTI. A statistical model of the received signal is formed using the derived deterministic target signal, and gaus- sion …

Geosynchronous Satellite Maneuver Classification and Orbital Pattern Anomaly Detection via Supervised Machine Learning
… orbital regime, where space objects orbit the Earth once per sidereal day, GEO satellites can appear fixed to a position in the sky when observed from the Earth’s surface. This unique orbital characteristic makes GEO satellites ideal for telecommunications missions that require Earth-fixed …

Measurement of aerodynamic characteristics of MAVs using motion tracking
… to help better understand the behavior of fixed-wing MAVs. In the current research, aerodynamic and stability characteristics of two MAVs were measured using a motion tracking system. Both the aircraft position and propeller rotation were tracked. The aircraft used were flat foam surface, …
