Proportional Navigation vs an Optimally Evading, Constant-Speed Target in Two Dimensions

摘要

A study of the behavior of a pursuer using proportional navigation against an evading target is presented. The target flies an evasive trajectory which will maximize the point of closest approach. The target maneuvers fall into several distinct classes depending upon the conditions at the initialization of the encounter. The target is assumed to have a one second lag in its control system and 5 g hard limits on its lateral acceleration. The pursuer is assumed to have a time lag in its guidance system and a soft g-limit on its lateral acceleration. (Author)
