This paper presents an interacting multiple model (IMM) based procedure to estimate the state of thrusting ballistic projectiles in the atmosphere for the purpose of impact point prediction (IPP). The modes of the IMM estimator are for the thrusting and the ballistic phases and different extended Kalman filters (EKF) are used as the mode-matched filters with different dimension states. The IPP is achieved by using the IMM-predicted most probable mode at the mid-point of the trajectory.
