For improving the precision and speed of missile's state estimation,IMM-UKF( TASIMMUKF) filtering method was proposed. In this algorithm,CV,CA,CJ model were built and the missile movement information was separated into three axes,so as to eliminate the cross coupling problem between difference axes in missile state estimation. Aiming at solving the nonlinear of measurement equations,UKF,which is of high precision,was adopted. Simulation results indicate that the new algorithm improves the accuracy of state ...
