前言自行高炮火控系统的备用计算机用于快速解算火炮的射击诸元。在敌机直线临近飞行时对保卫目标和自行高炮均处于最大威胁的情况下,利用光学跟踪座标仪和火控备用计算机,可以缩短计算射击诸元的时间,因而能比较快地开火。其特点是:不求取目标飞行速度、不考虑修正因素、计算射击诸元的时间较短、计算的是射击诸元提前角△β和△ε。“猎豹”自行高炮的火控系统配有这种备用计算机,其 Foreword Self-propelled anti-aircraft fire control system spare computer used to quickly calculate howitzer shooting elements. Using the optical tracking coordinates and the fire-control standby computer, it is possible to shorten the time required to calculate the firing elements and thus fire faster, while the target of attack and the self-propelled anti-aircraft artillery are at greatest threat as the enemy plane approaches the line of flight. Its characteristics are: do not seek the target flight speed, regardless of the correction factor, the calculation of the shooting time is shorter, the calculation of the shooting element advance angle △ β and △ ε. “Cheetah” own anti-aircraft artillery fire control system equipped with such a spare computer
