Abstract
- The inherent Doppler blind zone (DBZ) of airborne early warning radar can bring out target track termination with the worse effect in multi-target and clutter environment. Based on two-dimension assignment algorithm with DBZ information, a new plot-to-track association method based on multi-dimension assignment algorithm is proposed. Firstly, the evolution information of target track is used enough, and the radar's continuous multi-frame measurement data are used to perform sliding window processing. Secondly, the cost function of multi-dimension assignment is constructed. Finally, the solution of function on the condition of minimal cost is used as the targets plot-to-track assignment solution. The simulation results show that this method has further descent of track termination rate compared with two-dimension assignment algorithm in multi-target and clutter environment with DBZ.
