【 摘 要 】

The goal of this Phase II SBIR has been to develop a prototype software package to demonstrate spectrally-aided vehicle tracking. The primary application is to show improved target vehicle tracking performance in complex environments where traditional spatial tracker systems may show reduced performance. Examples include scenarios where the target vehicle is obscured by a large structure for an extended period of time, or where the target is engaging in extreme maneuvers amongst other civilian vehicles. The target information derived from spatial processing is unable to differentiate between the green versus the red vehicle. Spectral signature exploitation enables comparison of new candidate targets with existing track signatures. The ambiguity in this confusing scenario is resolved by folding spectral analysis results into each target nomination and association processes. The work performed over the two-year effort was divided into three general areas: algorithm refinement, software prototype development, and prototype performance demonstration. The tasks performed under this Phase II resulted in the completion of a software tool suitable for evaluation and testing of advanced tracking concepts.
