Abstract:

The type observation set of members within a group target is often incomplete and uncertain due to the limited performance of the sensor and the processing algorithm. And the group targets’ composition templates are usually unfixed. Taking these practical conditions into account the tranditional group target composition recognition methods based on fixed template matching are no more applicable. Aiming at the problem a group target composition recognition method based on unfixed template matching is proposed. Firstly, the type observations of members within a group target and the composition template in the template base are described. Secondly, the interval distance measure between the type observation set and each unfixed composition template is calculated. Finally, the observed group target’s composition is recognized by sorting the interval distance measure. Simulation experiments validate the effectiveness of the proposed method.
