Air Target Intention Recognition Based on Incomplete Multi-Granulation Rough Set

In this paper, an incomplete Multi-Granulation Rough Set (incomplete MGRS) is presented to recognize the intention of the air target. First, the model of the air target intention recognition based on the incomplete MGRS has be constructed, the dynamic change rate of the air target state has been added into the condition attribution of the decision to enhance the air target intention recognition capability under incomplete information and dynamic environment. And then some measures and a attribute reduction algorithm based on the importance of the decision attribute are presented. Finally, the simulation results showing that the decision algorithm based on the incomplete MGRS can recognize the intention of air target effectively under complex and uncertain combat environment.
