【摘要】：针对遥测设备现有记忆跟踪存在速度跳变和外推误差大的问题,提出了一种基于理论弹道速度匹配的记忆跟踪算法。分析了遥测设备记忆跟踪算法原理与不足,对原记忆跟踪算法进行改进,同时将Neville算法用于记忆跟踪数据插值。仿真结果表明新算法外推10 s、5 s和3 s的均方根误差比原算法平均减小44.9%。新算法在设备应用的测试结果同样证明了其优越性。
[Abstract]:Aiming at the problems of speed jump and large extrapolation error existing in the memory tracking of telemetry equipment, a memory tracking algorithm based on theoretical trajectory velocity matching is proposed. The principle and deficiency of telemetry device memory tracking algorithm are analyzed. The original memory tracking algorithm is improved and Neville algorithm is used to interpolate the memory tracking data. The simulation results show that the root-mean-square error of the new algorithm is 44.9 less than that of the original algorithm. The test results of the new algorithm in the application of the equipment also prove its superiority.
