A New Algorithm for Data Fusion of the Trajectory Computing Only with the Velocity and Its Application

In this paper,to resolve the problem of data fusion for the trajectory computing only with the velocities,much matter including the confirmation of initial value,the searching of the optimal knots,the selection of the base spline function and the numerical solutions of the model of the data fusion is discussed and analyzed,and then a new algorithm of the data fusion is brought forward,which is applicable to computing the trajectory only with the velocities.With the application in several missile trials,it indicates that the algorithm has not only favorable astringency and stability,but also has good effects,and the precision of the trajectory computed by using the algorithm is similar to the precision computed with the "position-velocity" condition.
