Paper Abstract

This paper outlines a concept for exploiting UAV (Unmanned Aerial Vehicle) trajectories for detecting slowly moving targets. All the analysis and simulation results are reported under the assumption of a circular UAV trajectory with various degrees of localized perturbations in the neighborhood of a given circular trajectory. These trajectory perturbations are introduced and investigated in order to develop intelligent processing algorithms for purposes of detecting slowly moving targets. The basic concept is based on collecting sub-apertures of data over a given set of localized trajectories and intelligently parsing the collected data based on time-varying angle estimates between the localized UAV trajectory and subsets of a collection of moving point targets. This parsed data is intelligently combined over large SAR integration sub-intervals and intervals to develop a novel approach to detecting moving targets with large variations in speed and target trajectory. Simulation results are reported for three different trajectory perturbation functions.
