The Realization of the Proportional Guidance in the Laser Terminal Guidance System of Maneuver Warhead

The proportional guidance is one of the guidance laws which is researched popularly and applied extensively at present.We would try to apply it for designing the project of the laser terminal guidance system of maneuver warhead in this paper.After analyzing the running principle of some type of laser seeker,the forming process of the proportional guidance signal was discussed and the predigested control model of seeker's loop was established. Because terminal control of maneuver warhead can be decomposed into pitching control and yawing control,we separately designed proportional guidance parameters of their hy applying Linear Quadratic Optimal Control Theory which might he able to offer some references for the next phase of engineering design.
