摘　　要：传感器测量的准确与可靠是减小融合系统不确定性的前提,通过对多传感器一致性的检验,可以确定多传感器之间的测量误差,判断检测系统可靠性的程度。提出了应用概率距离测量对多传感器信息进行一致性检验的方法,并将此方法引入到基于多惯性测量组合的总线式导弹制导控制系统中。实例证明,该方法对于确保和提高测量导弹飞行信息的精度具有良好的效果。The accuracy and reliability of the measurement by the sensors is the prerequisite of lowering the indefiniteness of the fusion system. By means of the consistency cheek, the error between the measurements made by various sensors can be determined and the reliability of the system can be adjusted. The method for consistency cheek of multisensor data by using the probability distance measuring is presented, and it used in CAN bus missile guidance and control system based on muhi-IMU. Application proves the method effective to improve the measuring aeeuracy of missile flying information.
