Non-linear automatic target tracking in clutter using dynamic Gaussian mixture

This study presents a complete algorithm for single target tracking in clutter, which addresses simultaneously: non-linear measurements; uncertain target detections; presence of random clutter measurements; and uncertain target existence. Proposed algorithm generalises the integrated track splitting (ITS) filter by extending the ITS functionality to highly non-linear measurements. The non-linear target tracking and estimation problems may also be solved by application of particle filters, albeit incurring a significant computational expense relative to proposed solution. In an environment without data association uncertainties proposed filter becomes a non-linear estimator.
