摘　　要：为了减小可编程电子时间引信计转数测速误差,提高炸点精度,分析了现有平均值法转数数据提取策略对干扰数据无法有效剔除的情况,考虑到中位数不受干扰数据影响并可准确反映出主体数据特性,提出了一种利用中位数法对引信转数数据提取的方法,并将该方法与快速排序法相结合,提高了软件执行速度。为了验证所提方法的有效性,设计了模拟引信测速系统。采用多组靶场回收到的弹道数据进行验证,结果表明,中位数法引信测速值与雷达测速值测速偏差率为0.21%,采用平均值法测速偏差率为0.975%。采用该文中位数法对转数数据进行筛选,提高了引信测速精度,可为计转数测速引信的设计提供参考。In order to reduce the velocity measurement error of programmable electronic time fuze and improve the accuracy of burst point,the situation that the existing rotation data extraction strategy based on the average method can not effectively eliminate the interference data was analyzed.The median is not affected by the interference data,and it can accurately reflect the characteristics of the main data.Considering the problem,a method of fuze rotation data extraction based on the median method was proposed.Combined with quick sort method,the software execution speed was improved.In order to verify the effectiveness of the proposed method,a simulation fuze velocity measurement system was designed.Through the verification of trajectory data collected from multiple ranges,the velocity deviation ratio between the median fuze velocity measurement value and the radar velocity measurement value is 0.21%,and the velocity deviation ratio of the average method is 0.975%.It improves the accuracy of the fuze velocity measurement to filter the revolution data by using the median method,which can provide reference for the design of revolution velocity measurement fuze.
