ANALYSIS OF OPTIMAL EVASIVE MANEUVERS BASED ON A LINEARIZED TWO-DIMENSIONAL KINEMATIC MODEL

摘要

Optimal evasion from proportionally guided missiles is analysed assuming two-dimensional linearized kinematics. By this assumption a simple search technique can be used instead of the cumbersome solution of a two point boundary value problem. Due to the simplicity of this approach it is possible to include in the mathematical model factors which have been neglected in other analytic studies. It is demonstrated that these factors as:the exact dynamic structure of the guidance system, the location of the saturating element in the guidance loop, the limited roll rate of the evading aircraft, etc., have major effects on the optimal maneuver sequence and determine the order of magnitude of the resulting miss distance.
