测速定轨中的递推样条滤波算法

针对传统方法在全测速体制下实时处理能力不足，建立了基于递推样条模型的实时滤波算法。算法通过提高测量信息利用率，迭代更新模型参数以快速适应弹道的时变特性。仿真和实测数据的计算结果表明，算法鲁棒性较好，在平稳段落精度优于其它方法。算法就全测速体制的主动段弹道估计问题展开，但其原理具有一定的普适性。 

Recursive Spline Filter Algorithm for Orbit Determining Utilizing Range Rate

In respect that traditional methods have essential deficiency for orbit determining utilizing range rate only,filter based on recursive spline modeling is derived.The filter can fit trajectory maneuvers effectively by iteratively recursive updating model parameters.Simulation and actual test indicate that the filter performs robustly,and has higher accuracy during smooth fragments than traditional methods.Although developed for boost phase and velocity measurements,the filter has universality in principle.
