Abstract

For highly maneuvering targets, the target model was built in Cartesian coordinates based on "current" statistical model. Since target state model was linear and measurement model was nonlinear, the two-step filter was used. Adaptive filtering was a-chieved by an online estimation of target acceleration variance and measurement noise variance. For highly maneuvering targets, simulation results show that the estimator's errors can converge more rapidly and are less than EKF estimator's errors. So the tar-get state estimator is applicable to infrared imaging missile for highly maneuvering targets.

Key words： guidance and control; measure-only line-of-sight angular velocity; target maneuver; adaptive; two-step filtering algorithm
