Impact-Angle-Control Guidance Law with Terminal Constraints on Curvature of Trajectory
This paper presents an impact-angle-control guidance law with terminal constraints on the curvature of the missile trajectory. The formulation takes into account nonlinear kinematics and time-varying velocity, allowing for more general cases in which the

Integral Global Sliding Mode Guidance for Impact Angle Control [PDF]
This paper proposes a new guidance law based on integral sliding mode control (ISMC) technique for maneuvering target interception with impact angle constraint. A time-varying function weighted line-of-sight error dynamics, representing the nominal guidance performance, is introduced first.

Bezier-curve Navigation Guidance for Impact Time and Angle Control [PDF]
This paper addresses a novel impact time and angle control guidance law using a Bézier curve. The 2nd order Bézier curve consists of one control point and two boundary points; initial point P0, middle point P1 and end point P2.

Definition of Impact Angle and Impact Angle Control Law Against Maneuvering Target
In this paper, a guidance law for intercepting maneuvering target with a desired impact angle is proposed. The proposed guidance law is modified from the optimal impact angle control law for a fixed target and given by a biased PN law with the impact angle control term in addition to the conventional PN law.
