Passive Homing Missile's Variable Structure Proportional Navigation with Terminal Angular Constraint

摘要

The objective is to design a variable structure proportional navigation law for the passive homing missile so that the missile can hit the target with a minimum miss-distance and desired impact attitude angle within the required overload when it files at a lower trajectory. This paper utilized the variable structure propor- tional navigation with terminal impact attitude angular constraint, and made estimation about the distance rate and distance between the missile and target, which broke the limitation o a passive homing seeker.
