This paper considers trajectory optimization for missiles to enhance the capability to estimate target locations during the attack phase. Using a cost function based on the determinant of the Fisher information matrix, a suboptimal guidance law which satisfies the field of view constraint and dynamics constraints is designed with single step method. The guidance law has a simple structure and can...
For issues that external uncertain disturbances and parameters perturbation can result in low guidance accuracy as well as poor robustness in traditional terminal phase, an optimal sliding mode guidance law with impact angle constraint was proposed. Firstly three-dimensional mathematical model of missile-target relative motion was established based on point mass assumption, then linear quadratic regulator...
