运载火箭靶场测试数据包括遥测无线测试数据和地面有线测试数据。参数数量巨大,数据类型繁杂,人工判读测试数据工作量大、效率低、判读准确度难以控制。为适应靶场高密度任务形势需要,针对靶场几类参数,采用中值滤波算法实现了台阶参数和脉冲参数的滤波平滑处理;创造性设计了双边多点阈值判断方法与符号判读方法相结合的台阶识别算法,实现了台阶的自动准确识别;引入6σ原则,实现了脉冲参数的脉冲识别和统计;并对每个台阶进行滤波前后的数理统计,实现了自动辅助判读功能。该方法的成功应用,有效提高了发射场数据判读比对效率和判读准确性,为中心做出准确高效决策提供有力支持。
The launch vehicle range test data includes telemetry wireless test data and ground wired test data. The number of parameters is huge, the data types are complicated, the workload of manual interpretation of test data is large, the efficiency is low, and the accuracy of interpretation is difficult to control. In order to meet the needs of the high density mission, aiming at several parameters of the shooting range, the median filtering algorithm was used to filter the smoothing parameters of the step parameters and the pulse parameters. The method of combining the multi-point threshold judging method with the symbol judging method was creatively designed. Algorithm to realize the automatic and accurate identification of the steps. The 6σ principle is introduced to realize the pulse identification and statistics of the pulse parameters. The mathematical statistics before and after each step are filtered to realize the automatic auxiliary interpretation function. The successful application of this method effectively improves the efficiency and interpretation accuracy of interpretation data of launch site data and provides strong support for accurate and efficient decision making at the center.
