NetTrack
Abstract
The NetTrack Program developed feature-aided tracking technologies to enable airborne surveillance radars to maintain track on moving high value targets (HVTs) in traffic and cluttered environments. Ground moving target indicator (GMTI) radars provide excellent potential for tracking HVTs because they operate in all weather and at long ranges. However, maintaining target tracks is very challenging because obscuration and close target spacing make it difficult to associate radar kinematic measurements over time. To address this challenge, NetTrack developed feature aided tracking technology that automatically collects and exploits target high range resolution (HRR) radar measurements. Specific NetTrack technologies include signal processing to generate HRR measurements from raw radar returns, feature extraction and matching to exploit HRR measurements, multiple hypothesis tracking to associate measurements to tracks and estimate target location and velocity, and sensor resource management to automatically select optimum radar mode parameters and timing sequences. A Memorandum of Agreement (MOA) has been established for transition of NetTrack to the Navy Advanced Airborne Sensor which is a follow-on to the Navy Littoral Surveillance Radar System.
