摘　　要：讨论了D -S证据推理理论 ,给出了传感器特征信息融合算法。结合卫星天线振动频率分配控制问题 ,进行相应的实验研究 ,对传感器的特征信息进行融合 ,给出了振动响应频率特征信息提取方法 。The theory of D-S evidence reasoning is discussed and the algorithm of fusion of the sensors' characters information is given in this paper. In an example of vibration frequency distributing control of the satellite antenna, the experimental study has been performed and the fusion of sensors' characters information is made, the extract method of vibration frequency eigenvalue is given. This eliminated the boundary condition effect to the believed degree of the testing result.
