摘　　要：针对大射程导弹试验对遥测数据对接的处理要求,分析了现有数据对接方法的不足和局限性,提出了基于互累积量的遥测数据帧时延估计方法,并实现遥测原始数据的精准对接.试验数据测试表明,该方法能够精确估计遥测数据的帧时延,实现对接遥测数据的帧时间修正,保证遥测数据帧时间和数据的连续性与一致性,剔除大量噪声数据,提供高质量的全程遥测数据.Aiming at the processing requirements for telemetry data-joining in long-range missile test,the shortage and limitation of the data-joining methods in existence are analyzed,and a new method which estimates telemetry data frame-time-delay based on higher-order statistics is presented and the accurate data-joining of telemetry original data is realized.Simulation results on test-data show that the proposed method can accurately estimate the frames-time-delay of telemetry data,and revises the frames time of joining-data,ensures the consistency and continuity among frames time and data of telemetry,simultaneously eliminates a mass of zebra outliers,provides top-quality full-range telemetry data for data processing.
