基于中值滤波实现遥测视速度数据异常值识别

摘要

Duo to the fault recording equipments and measurement accuracy limit of the test procedure and other fac-tors,the abnormal value is unavoidable in telemetry data.To solve this problem,the median filter is used to abnormal value identification of telemetry apparent velocity data.The abnormal value data processing procedure is set up.The identification results of the abnormal data of the positive and negative channel under bit error rate=0.005 are given.And it has been used in the tests.Good results have been achieved.%在试验过程中,由于记录设备故障或测量精度限制等因素,遥测数据不可避免地存在异常值,针对此问题提出采用中值滤波实现遥测视速度异常值识别.制定了异常数据处理流程,给出误码率Pe=0.005时的仿真遥测正负通道异常值识别结果,并在试验任务中得到具体应用,取得很好的识别效果.
