摘要
文中提出将累积法应用到外弹道测量数据处理中,用以拟合导弹的飞行轨迹,估计导弹飞行的速度参数。设计了累积法的通用计算机程序以简化其计算过程,简单比较了累积法和最小二乘法的优缺点。最后通过一个实例证明累积法的求解效果要稍优于最小二乘法。
The paper presents the application of cumulative-sum method in the field of external trajectory measurement data processing to fit ballistic trajectory and estimate missile's velocity parameters.The general computer program of cumulative-sum method is designed to simplify its calculation processing.The cumulative-sum method is compared with the least-square method,and its advantageis verified through analyzing a ballistic trajectory.
