Multi hypothesis track extraction and maintenance of GMTI sensor data

This contribution presents an application of a multi hypothesis tracking (MHT) algorithm to the case of ground moving targets detected by GMTI (ground moving target indicator) sensors. We describe in some detail how the following tracking tasks are performed: track extraction, prediction, filtering, track maintenance and retrodiction (smoothing). The experimental implementation has been successfully tested in a NC3A (NATO Consultation, Command and Control Agency) testbed with simulated GMTI data of various ground surveillance sensors. Ongoing developments and improvements are discussed.
