Focusing on the possibility for observed results with false or erroneous information of a sensor to affect data fusion estimation,an operator measuring consistency of the observed results of a multi-sensor is introduced.Before data fusion estimation,the consistency checking on the observed results is taken to identify and remove the observations of failed sensors,and obtain the consistent estimating.Based on the Hampel gross error identifier,the consistency measuring operator is able to take both self-support and mutual support between the sensors into account,to obtain the consistency information of observations.The simulation shows the simplicity and effectiveness for identifying false and erroneous observed results,eliminating the failed sensors,evaluating the quality of each sensor observations,and providing data fusion estimation with reliable consistent sensor group.
