Wei Wu · Aerospace Control · 2009
In order to improve the reliability and precision of data fusion processing of multi-sensor,data multi-scale distributed fusion estimation algorithm is put forward for estimating the data of multi-sensor based on Kalman filter.The algorithm firstly establishes the system dynamic equation and observation equation,then the data is processed on different scales by wavelet transform,and realization steps of the algorithm are induced and concluded.Finally,by the simulation in the GPS/INS,the result testifies that the algorithm can improve the precision of data processing in multi-sensor.
