Abstract: The main goal of this thesis is to obtain reliable outputs, which requires robustness relative to the noise included in input data and to the sensor deterioration or even the missing of the sensor. Without of any pre-defined knowledge concerning sensors，the multi-sensor data level fusion model based on artifical neuron can be used for the estimation of fused data with minimum mean square errors through observed data so as to calibrate the fusion neuron. Simulation results show that the fused data are much more sensitive，accurate，reliable than that of single sensor data .
