Abstract
A method for target motion analysis for calculating the track between an observer and a target and estimating its uncertainty includes initializing strongly observable state components into strong state vectors and weakly observable state components to form a weak state analysis grid. Initial probability density functions are calculated from all components. The method then iteratively calculates strong state gradients, target track direction, and updates strong state vectors over the analysis grid. Probability density functions are recalculated. Calculations are reiterated if the probability density functions change more than an information threshold. The strong state vectors and weak state probability density functions are provided as output if the information threshold is not exceeded.
