模糊相似性及D-S理论的目标识别融合方法

由于试飞环境的复杂性和噪声干扰等因素的影响,使得对空中目标的识别存在一定的不确定性,为了提高目标识别的正确率,根据传感器对目标的测量,提取的目标特征信息,依据模糊相似性测度,得到传感器报告的信任度,以信任度作为加权系数对各测量的隶属度进行加权决策,再依据D-S证据组合规则,最终得出目标识别融合的结果.给出的方法能在复杂试飞环境中有效地识别目标.基于模糊及D-S理论的目标识别融合方法具有实现简单、运算量小和识别结果可靠等优点,具有一定的理论意义和实用价值.

Research of Target Identification Fusion Method Based on the Fuzzy Matching and the D-S Theory

Because of the influence of the complexity environment and noise jamming,target identification is uncertain in the flight-test examination.To enhance the preciseness rate in target identification,target characteristic information is extracted based on the measurement of the target by the sensor.The subjection degree relative to the reference target in the target storage is calculated via maximal subjection degree principle.The trusting degree of the sensor is gained via D-S theory.Fusion target identificati...
