| Abstract: | A homing guidance law against a high-speed target in the exoatmospheric area is proposed based on the vector field approach. The vector field is designed and utilized to achieve head-on hit-to-kill interception. The trajectory of the target is predicted using the gravity acceleration model. The vector-field-based guidance law makes the missile converge to the predicted trajectory of the target, and therefore, the missile can await the target by flying along the predicted trajectory. The shape of the vector field is designed with the consideration of the smooth convergence and finite-time convergence, and the corresponding bounding condition imposed by the lateral acceleration limit is derived. The feasible region for the parameters in the finite-time convergent vector field is analyzed, and the performance of the proposed guidance law is demonstrated using numerical simulations.
