SDRE Guidance Law for Impact Angle Control against Moving Targets
In this paper,the terminal guidance problem of intercepting a moving target along a predetermined direction in the planar engagement scenario is considered.In this problem,two design specifications must be achieved: one is the minimum miss distance; and the other is the specified terminal impact angle.This problem is formulated as an infinite-horizon nonlinear regulator problem,and solved using the state-dependent Riccati equation (SDRE) method.To obtain a finite-horizon guidance law,a time-to-go based state weighting matrix is employed in the SDRE control scheme.In addition,to maintain the missile and the target in collision course and reduce the time-of-flight,the missile-target relative look angle is restricted using the SDRE control with a state constraint.Nonlinear simulations are performed to demonstrate the basic properties,applicability and robustness of the proposed guidance law.
