Based on the L1 guidance law,this paper proposes a track tracking method for loitering missiles.Course tracking is divided into circular course tracking and straight course tracking.According to the geometric relationship between the initial po-sition and the theoretical course,the expressions of the leading angle under different states are derived,and the circular course and straight course tracking strategies are proposed to ensure that the loitering missile can fly along the theoretical course with-out overshoot.Finally,the simulation results show that the proposed guidance strategy has good tracking effect on circular course and polygonal course.
