TLDR
In this paper, a new homing guidance law is proposed to impact a target with a desired attitude angle, which is a variation of the conventional proportional navigation guidance (PNG) law which includes a supplementary time varying bias.Abstract:
A new homing guidance law is proposed to impact a target with a desired attitude angle. It is a variation of the conventional proportional navigation guidance (PNG) law which includes a supplementary time-varying bias. The proposed guidance law does not require a time-to-go estimation and has a simpler form. Analytic conditions for fulfilling the guidance goal are also provided. Simulation results demonstrate that the proposed guidance law has wider launch envelopes than the previous one and shows a good performance even against a maneuvering target.read more

Impact-time-control guidance law for anti-ship missiles
TL;DR: A new guidance problem with the impact time constraint is investigated, which can be applied to salvo attack of anti-ship missiles and the closed form solution based on the linear formulation is derived, suggesting an additional loop for adjusting the impactTime in addition to the traditional optimal guidance loop.

Optimal Guidance Laws with Terminal Impact Angle Constraint
TL;DR: In this article, the optimal guidance command is represented by a linear combination of the ramp and the step responses of the missile's lateral acceleration, which is derived in the form of the state feedback for the lag-free and the first-order lag system.

Guidance law to control impact time and angle
TL;DR: In this article, a new guidance law is proposed to control both impact time and impact angle for a flight vehicle's homing problem, which can be applied for an efficient salvo attack of antiship missiles or a cooperative mission of UAVs.

Fundamentals of proportional navigation
TL;DR: In this article, the basic theory of proportional navigation is presented and two variations on this guidance method are treated: one in which the commanded acceleration is biased by a small value of the measured rotational rate of the line of sight between the interceptor and its target.

A Lyapunov-like approach to performance analysis of 3-dimensional pure PNG laws
Seong-Ho Song,In-Joong Ha +1 more
TL;DR: It is proved that a missile guided by the 3-dimensional PPNG law can always intercept a target maneuvering randomly in the3-dimensional space if 1) the target acceleration varies with a known bound, 2) the navigation constant is selected large, and either 3a or 3b the initial heading error is small.
