Abstract:

When the sensor information of the target recognition system is highly conflict, integration can not be effectively carried out only using the D-S combination rule. A target recognitive method based on evidence theory is presented. On the basis of defining a conflict coefficient, a target recognitive method is designed. When conflict is low, the D-S combination rule is used directly. On the contrary，according to the specific circumstances of conflict evidence, the evidence is discounted firstly and then is fused and intergrated. Compared with other methods, simulation experimental results show that this proposed method can improve the anti-jamming ability and has a faster convergence speed.
