Due to the use of strapdown seeker in small missiles, a small field of view angle is required to ensure effective tracking and strike of the target during the final interception.Based on the tracking strategy of dragonfly chasing targets, a composite guidance law is studied.In the initial guidance section, the parallax angle is controlled by the sliding mode control law to adjust the missile to the tail following attitude.The click here final guidance section used the motion camouflage guidance law with the focus at infinity for target tracking,and between the initial guidance and the final guidance.

The second-order smooth interface law is used for the transition.The simulation results show that compared with the traditional proportional guidance law, the required overload of the missile in the final guidance is small,and the target is closer to the center of the field of view, which can reduce the missile in the final guidance.The overload and the field of view of the seeker can be used to hindigyanvishv.com effectively improve the attack accuracy.
