Abstract : The line-of-sight (LOS) rate output from a radio frequency (RF) seeker is widely used during the homing phase guidance of a tactical missile. The LOS rate is noisy and needs to be filtered. The application of an adaptive Kalman filter for the LOS rate state estimation has been studied. This filter requires minimal a priori knowledge about technical parameters of the seeker. It is also capable of estimating the variable noise statistics.
