基于证据理论的空中目标识别

Identification of Air Targets Based on Evidence Theory

针对证据理论在处理冲突证据时可能得到与直觉相悖的结论,提出一种新的基于权值的证据调整方法,当证据互相冲突时,不必修改合成规则,直接对各组证据赋予不同的权值调整概率分配函数.仿真数据表明,通过证据调整方法进行空中目标类型识别可行,并且实现了可靠的目标判定.

It is invalid when the evidence theory is used to deal with conflicting probabilities. In this paper, a new weighted D-S combination rule is proposed to solve the conflicting management in the air target identification system. In the weighted method presented here, it is to modify evidences rather than to modify the combination rule. The rationality and effectiveness of the weighted method are evaluated by the target identification system.
