A nonlinear guidance law considering the constraint of impact angle is developed by employing the state-dependent Riccati equation (SDRE) technique. The planar guidance problem is first converted to a nonlinear regulator problem which aims to concurrently zero line-of-sight (LOS) angle error and rate. Then under the framework of the SDRE technique, a nonlinear guidance law with two tunable gains is obtained. Finally, the effectiveness of the nonlinear guidance law is confirmed by several simulations.
