Abstract:

Influened by the detection performance and observation noise of a sensor, the position observation set of members within a group of targets is often incomplete and uncertain and usually contains clutter. The conventional group target formation recognition methods based on fixed datum mark are no more applicable on these practical conditions. Aiming at the problem, a general method for group target formation recognition is proposed. The method selects the datum mark dynamically depending on the different formation templates and formation observations, which restrains the effect of missing detection, position noise and clutter on the formation description for group targets effectively. The formation of the observed group target is recognized by matching of its formation description and that of the formation templates. Simulation experiments validate the effectiveness of the proposed method.
