Improved command to line-of-sight for homing guidance

The command to line-of-sight (CLOS) guidance is known to require very high acceleration commands as the distance between a missile and its target becomes closer. Therefore, the CLOS is generally used for midcourse guidance. In order to use the CLOS for homing, an additional feedforward acceleration command (FFC) is necessary. In this correspondence an improved CLOS (ICLOS) technique which includes FFC is proposed. Its performance improvement is demonstrated by applying the technique to a surface-to air missile (SAM).<
