This study proposes a look angle rate minimizing optimal guidance law with impact angle control and look angle limit. The optimal control theory is adopted to solve the look angle rate minimization problem which has the state inequality on the look angle limit and constraint for impact angle control at the final time. The performance of the proposed guidance law is shown demonstrated by simulations for engagement scenarios of several look angle limits and impact angle constraints. The comparative study shows that the proposed guidance law outperforms on the energy and look angle managing ability.
