引言在大多数已发表的论述比例导引的著作中,都假设目标和导弹的速度为常数,近距离时,如果导弹维持恒定的相对方位,就能够保证对非机动目标的截击。为了维持这个恒定的方位角,比例导引导弹试图使视线速率为零。轴向加速或减速可能严重地影响比例导引导弹的性能。这有两个主要原因,第一, INTRODUCTION In most of the published papers on lead ratio propositions, it is assumed that the targets and missiles are constant velocities, and that at close ranges the non-maneuver targets can be intercepted if they maintain a constant relative orientation. In order to maintain this constant azimuth, the proportionally guided missile attempts to keep the line of sight rate at zero. Axial acceleration or deceleration can seriously affect the performance of the proportionally guided missile. There are two main reasons for this. First,
