摘要
针对全测速体制下现有弹道估计方法实时处理能力的不足,提出了基于滑动多项式表示弹道的测速定轨算法.详细推导了算法过程,讨论了迭代初值、窗口宽度和弹道拼接等关键技术,利用仿真实验对算法性能进行了综合验证.该新算法利用了弹道光滑特性和求导匹配特性,可以增强数据冗余,提高解算精度;短时窗口的采用降低了算法的复杂度,减缓了解算滞后问题.
Aiming at the inherent shortcomings of traditional algorithms for trajectory determining by use of rate data in real-time requirement, polynomial representation algorithm with sliding window was proposed. The new algorithm was detailedly derived with a discussion about some key techniques such as initial value, width of sliding window and method of trajectory link. Simulations were used to verify its performance. Utilizing of the smoothing and matching character, the new algorithm has a higher accuracy in trajectory tracking. By short window technique, the calculation complexity is reduced, and the lag between tracking and observation is relieved.
