Abstract :
Kalman filter used in seeker system for target tracking may induce low precision because of the equation linearization and the real time tracking performance of the seeker may be broken down. A real time Kalman filter with high precision is introduced and this algorithm is deduced in the line of sight reference frame via coordinate transformation. The effectiveness of the algorithm is shown trough numerical simulations.
