Abstract:
Main control challenge with sea skimming cruise missiles is to achieve the lowest possible flight altitude over mean sea level during midcourse guidance phase in order to reduce its detectability against targeted warships. Contrariwise, realizing a very low altitude is a rough objective under realistic disturbances due to sea waves and measurement errors of many sensors used in the altitude control loop. Therefore, a robust altitude controller is needed to be applied to height control loop of anti-ship missiles. In this study, Kalman filter based altitude control method is proposed and compared with the existing designs in literature. Moreover, determination of the optimal flight altitude is performed by estimating the instantaneous sea condition by Kalman filter. Simulation results for widely varied scenarios, in which different sensor errors, sea conditions and discrete time applications are taken into account, are shared. Simulation results indicate that the proposed altitude control system design has pleasing performance under realistic real world conditions. Key words: sea skimming guidance, robust altitude control, Kalman filter based estimation, sea wave optimal flight altitude

Keywords: Sea skimming guidance; Robust altitude control; Kalman filter based estimation; Sea wave optimal flight altitude
