| 摘 要： | 用速度平差法求解目标运动要素是潜艇作战中常用的目标运动要素求解方法.通过全面分析该算法的原理和求解过程,运用典型数值分析、数学归纳等方法,论证了目前速度平差法应用中求解过程的不完整性及漏根的根源,结合潜艇鱼雷攻击实际,采用迭代法和数轴验根法,提出了新的求解办法,提高了目标运动要素解算的可靠性和效率.

| Abstract: | The least square method about velocity is used usually to solve the essential factors of target motion in submarine operation.This paper analyses its principle and solving process,studies its unintegrity and the source that can lead to lead to leau root by means of numerical analysis and mathematical inductive method.A new solution is put forward using the iterative method and verifying root on the number axis in the light of torpedo attack practice.This method can improve the reliability and efficiency of solving the essential factors of target motion. |
