Missile guidance and pursuit

TL;DR: In this paper, the authors proposed guidance laws to intercept targets at a desired impact angle, from any initial heading angle, without exhibiting any singularity, by selecting interceptor's lateral acceleration to enforce nonsingular terminal sliding mode on a switching surface designed using nonlinear engagement dynamics.

TL;DR: By simultaneously tracking the position and orientation of a dragonfly’s head and body during flight, this work provides evidence that interception steering is driven by forward and inverse models of dragonfly body dynamics and by models of prey motion.

TL;DR: In many advanced guidance applications, it is required to intercept the target from a particular direction, that is, achieve a certain impact angle as discussed by the authors. But this is not the case in our case.

TL;DR: In this paper, an analytic solution for the time-to-go of the pure proportional navigation guidance law against a stationary target is derived considering full nonlinear engagement kinematics without near-collision course approximation.

TL;DR: In this paper, the authors developed guidance laws for tactical missiles which take into account the following important dynamic and random effects: random target motion, homing sensor measurement noise, bounded control level, bounded acceleration level, and missile autopilot dynamics.

TL;DR: In this article, it was shown that the pursuer can, without violating constraints, keep the line of sight parallel to the original and ultimately collide with the evader, provided the pursuers have greater speed and greater normal acceleration.

TL;DR: It is shown that the addition of an appropriate bias term to a proportional navigation guidance equation allows an interceptor missile to attain an efficiency which can be made to approach that of an optimum system.

TL;DR: Simulations and experiments with real mobile robots show that both capture probability and mean capture time are inversely related to the prey/pursuer speed ratio, and demonstrate that bat-like sonar represents an efficient sensing system.
