Abstract
In this paper, a robust horizontal LOS (line-of-sight) rate estimator for sea skimming anti-ship missile is proposed. A exact LOS rate dynamics model for two-axes gimballed seeker is derived in homing geometry. A new LOS rate estimator is designed by applying a robust Kalman filter to the LOS rate dynamics model. The proposed filter takes into account roll motions and detection gain uncertainties. Simulation results show that the proposed filter performs very well and guarantees the robustness against parameter uncertainties.
