摘要：AbstractIn the homing phase of a guided missile, a lock-on condition should be maintained to intercept a target. For a missile with a strapdown seeker, there exists a field-of-view limit that affects the lock-on condition. Therefore, the field-of-view limit should be considered to maintain the lock-on condition in the design of guidance law for missiles equipped with strap-down seeker. On the other hand, the impact angle and the impact time are significant factors to increase the effectiveness of the multiple missile system. In this study, a reference shaping method is proposed to satisfy the impact angle and time considering limits of the field-of-view and acceleration. A reference trajectory of the look angle is shaped using polynomials. For a given impact angle, range of the achievable impact times can be obtained via optimization. The reference shaping parameters for the impact angle and time can be numerically calculated. Numerical simulation is carried out to demonstrate the performance of the proposed method.
