Multi-sensor data fusion technology has been widely used in many fields.Multi-scale decomposition of wavelet has unique advantages to data analysis

and the choice of wavelet-basis play a key role to data fusion results.A new data fusion algorithm based on a number of wavelet is proposed.The multi-wavelet basis and scale wavelet decomposition to the sensor signals

and the weighted data fusion algorithm was implemented to signals of the same wavelet-basis decomposition on multi-scale

after the signal was reconstructed for inverse transformation of different wavelet-basis.Final fusion is carried out based on the reconstruction signal based on different wavelet.Experimental results show that the data fusion technology can be designed on the multi-side multi-levels and multi-fusion principles

in order to obtain the optimal results of multi-factors.
