【 摘 要 】

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 L.OS 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.
