高炮射击提前点的解法研究

针对高炮射击解提前点方法进行的研究,在图解法的基础上,运用解方程的思想,提出了精度更高的“系数调整法”、“图解逼近法”和“一元四次方程法”。较好地解决对匀速运动目标命中问题的求解,“图解逼近法”具有单方向收敛的优点。“一元四次方程法”可直接用消元法求解,不需循环。解法与迭代法比较,具有计算精度高、速度快,计算步骤、时间固定,在火控系统计算和修正等方面有重要的实用价值。

Research on Solution of Predicted Fire Point of Antiaircraft Gun

In the light of solution of predicted fire point of antiaircraft gun,on the basis of graphic method,by use of sulving the equation,the paper put forward solutions on precision higher:"adjust-coefficient method","graphic approach mehtod" and "quartic equation method".The methods can solve fairly good the hit problem of moving target at uniform speed.The graphic method has advantage of unidirectional convergence,and the quartic equation can be solved directly by elimination,need not the cycle,compared with the iteration,has high precision,fast speed and fixed time of calculation.In the field of trajectory calculation and fire correction,the methods have practical value.
