An engagement dynamic model is set up for the miniature missile guidance solution under the constraints of field-of-view angle and terminal impact angle. The impact-angle constraint guidance law design is converted into an optimal control problem subjected to terminal constraints. Then a look angle guidance solution without line-of-sight rate is detailed to satisfy the requirement on field-of-view and impact angles. The relation between the required maximal look angle and the terminal impact angle is analyzed and formulated. The proposed method is simulated and validated. The results show that a miniature missile could intercept a stationary target with the required impact angle.
