Tracking of a Missile Using Interacting Multiple Model

After thrust force of missile is off, many debris are created. The debris interferes with tracking the missile. Therefore, it is difficult to track the missile with a single Kalman filter. In this paper, we used Interacting Multiple Model (IMM) to solve the problem. Combining multiple models means that it considers many possible motions of missile, and it makes estimation accurate. This method is simulated with true trajectory derived from Modified Point Mass Model (MPMM). It is shown that proposed method improves estimation error.
