Pursuit-evasion using beam detection

Proceedings 2000 ICRA. Millennium Conference. IEEE International Conference on Robotics and Automation. Symposia Proceedings (Cat. No.00CH37065), 2002
We present an algorithm for searching a 2D environment for unpredictable moving targets using only beam-based detection. One or more pursuers move along the environment boundary, and carry a rotating beam that detects evaders. The beam could correspond in practice to a laser or a camera.

On Porter's pursuit-evasion games

Journal of Optimization Theory and Applications, 1970
A minimax problem for Porter's class of functionals is considered in the case when the two players' strategies are elements of convex and strongly or weakly compact subsets of real Hilbert spaces. Functional analysis is used to prove sufficient conditions ensuring the existence of saddle points.

On Function Space Pursuit-Evasion Games

SIAM Journal on Control, 1967
Functional analysis is used to analyze a minimax problem for a class of functionals on a Hilbert space. The abstract solution is then interpreted, through examples, in the context of pursuit-evasion games. The examples given are chosen to emphasize the breadth of the analysis. Some computational aspects of the minimax problem are considered.

Stochastic Linear Pursuit-Evasion Game

2012
The 1950’s saw the introduction of guided interceptor missiles and the launching of Sputnik I. Questions on pursuit and evasion were suddenly in everyone’s mind. What is the best strategy to intercept a moving target? How can friendly planes best avert midair collisions?

Stochastic multi‐player pursuit–evasion differential games

International Journal of Robust and Nonlinear Control, 2007
AbstractAutonomous aerial vehicles play an important role in military applications such as in search, surveillance and reconnaissance. Multi‐player stochastic pursuit–evasion (PE) differential game is a natural model for such operations involving intelligent moving targets with uncertainties.

Noisy satellite pursuit-evasion guidance

Journal of Guidance, Control, and Dynamics, 1989
Guidance laws are developed for both pursuer and evader satellites, using a simplified dynamic model of the one-on-one satellite encounter. Dynamic symmetry is assumed: both have noisy azimuth-elevation data, the criterion for each is the expected miss, and both satellites have on-off thrust inputs of controllable direction.

Vision-Based Pursuit-Evasion in a Grid

SIAM Journal on Discrete Mathematics, 2008
We revisit the problem of pursuit-evasion in a grid introduced by Sugihara and Suzuki [SIAM J. Discrete Math., 2 (1989), pp. 126-143] in the line-of-sight vision model. Consider an arbitrary evader Z with the maximum speed of 1 who moves (in a continuous way) on the streets and avenues of an n × n grid Gn.

A Note on Generalized Pursuit-Evasion Games

SIAM Journal on Control, 1975
Two player zero sum differential games are an extension of optimal control problems. When the cost or payoff is the integral of some function h up to the first time the trajectory enters a “terminal set” the differential game is one of survival. If $h \equiv 1$, the payoff is just the time elapsed up to the “capture time” and the game is one of pursuit
