Field-of-View Constrained Three-Dimensional Impact Angle Control Guidance for Speed-Varying Missiles
IEEE Transactions on Aerospace and Electronic Systems, 2022This article develops a three-dimensional (3-D) impact angle control guidance law with the field-of-view (FOV) constraint. The impact error is defined as the difference between the predicted impact angle by proportional navigation guidance and the ...

Field-of-view limited guidance with impact angle constraint and feasibility analysis
Aerospace Science and Technology, 2021A look angle shaping guidance law with impact angle and seeker's field-of-view (FOV) constraints considering the time-varying speed is proposed. A look angle profile with respect to the relative range is first constructed as a cubic polynomial.

Sliding mode–based simultaneous control of impact angle and impact time
Proceedings of the Institution of Mechanical Engineers, Part G: Journal of Aerospace Engineering, 2021In this article, a sliding mode control–based nonlinear guidance scheme for controlling both impact angle and impact time simultaneously is proposed. The problem of impact angle control is first transformed to that of controlling line-of-sight angle and ...

Impact-angle-constraint look angle guidance for miniature missile
2016 16th International Conference on Control, Automation and Systems (ICCAS), 2016An engagement dynamic model is set up for the miniature missile guidance solution under the constraints of field-of-view angle and terminal impact angle. The impact-angle constraint guidance law design is converted into an optimal control problem subjected to terminal constraints.

Look Angle Constrained Impact Angle Control Based on Proportional Navigation
AIAA Guidance, Navigation, and Control Conference, 2015Two guidance schemes for nonlinear impact angle control against stationary ground targets are presented to address the issue of the look angle constraint. The guidance laws utilized are the unbiased and biased pure proportional navigation laws, for which the necessary analytical solutions are derived.
