Design of instantaneous circular acceleration guidance law

In order to ensure the accuracy of the missile against target,we design an instantaneous circular guidance law according to the geometric properties of flat trajectory;the guidance law’s output command is an overload.The principle of instantaneous circular acceleration guidance law is described and the detailed derived equations of guidance law are also given.We obtain guidance overload command utilizing the centroid position and centroid velocity information of the missile and target when the missile attacks a target,we make a trajectory simulation finally.The simulation results illustrate that the instantaneous circular acceleration guidance law is not only hitting the target but also trajectory straight.
