Multihypothesis tracking with electronically scanned radar

Multihypothesis tracking (MHT) methods, well known for conventional radar data-processing, are generalized for phased-array radar application. We consider single targets in a cluttered environment. Suitable revisit and beam positioning algorithms are derived and optimized regarding the energy spent for tracking. In particular the destabilization of tracks due to clutter interference is analyzed. A comparison with a conventional algorithm (probabilistic data association filter (PDAF)) shows the saving of radar load which can be achieved by the proposed method
