单片空间后方交会，根据摄影比例尺，主焦距，影像坐标，地面坐标，计算出像主点的空间坐标和角元素。-Single space resection, according to photographic scale, the main focus, image coordinates, ground coordinates, calculated as the main point of the space coordinates and angular elements.

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 rota
