Abstract: The proposed Natural Tracking guidance law is designed to be completely robust in respect to the system internal dynamics and disturbance actions and could become an important alternative to the classic and modern guidance laws. It is capable to achieve impact angle demands (although with some limitations), even in the case of a moving target thanks to the Line-Of-Sight angle as the tracked variable. The Natural Tracking guidance law is  relatively easy to implement because it does not require the knowledge of time-to-go so it use only active homing head with angle sensors on board the missile. On the other hand, it requires a continuous control system, or a discrete one with very short sampling time to be implemented and has vast control effort requirements.

Keywords: natural tracking control, proportional navigation, impact angle, homing, missile.
