平行接近法弹道仿真。比例导航法，亦称比例导引法，是指导弹飞行过程中速度矢量 的转动角速度与目标视线的转动角速度成比例的一种导引方法。通过建模仿真，使大家更形象生动的理解平行接近法。-Parallel close to the law trajectory simulation. Proportional navigation law, also known as proportional navigation law the missile flight velocity vector rotation angular velocity of the rotation angular velocity of the target sight of the proportion of a guide. Through modeling and simulation, more vivid understanding of parallel close to the law.
