In structuring tactics for evading a pursuing vehicle

, it is often the case that the evader

does not know the intercept time.

\´s policy must by necessity be random, the precise definition being dependent upon the dynamic description of the vehicles and the geometry of the engagement. A method of designing efficient evasion tactics that apportions available maneuver effort over a time interval so as to make the expected pursuer miss distance independent of intercept time is presented. The evasion maneuvers are also structured so that

reaches the confines of some defended region, his ultimate goal.
