Due to data fusion of multi-sensor experiment on some characteristic indexes
a new fusion arithmetic for multi-sensor data is brought forward.The arithmetic defines the fuzzy similar matrix for the measurement of multi-sensor by the maximum and minimum method and determines the weight of entropy to value the weight of each sensor fusion.It may overcome the influence of subjective factor for the relationship matrix.The analysis for the experiment data shows that the method is simple
the connotation of data fusion is very clear and can avoid the loss of the effective data.
