The invention relates to a
flight test telemetering
data processing method, which belongs to the technical field of
flight test data processing, and comprises the following steps of: firstly, loading and preprocessing a
flight test telemetering
data file, drawing a curve of a measurement value of each measurement channel along with time change, and outputting a resolving
data file; specifying an interpolation method and a
time sequence, and outputting an interpolation table; the
time sequence of the interpolation table is converted into a monotone sequence, preprocessing is carried out,
timestamp verification is carried out,
outlier data are marked, 3 sigma
verification is carried out, abnormal data are eliminated, interpolation is carried out on the eliminated abnormal
point data according to previous and later data, and recalculation is carried out on the obtained interpolation table according to existing
telemetry data; a data cleaning rule is given, and a result is output after data cleaning. According to the method, accurate synchronization of the
time sequence of the heterogeneous
system can be realized, multi-mode abnormal data cleaning is supported, and the defects of high-frequency
information loss, poor abnormal value detection adaptability and low
processing efficiency during multi-source
telemetry data time
sequence alignment in the prior art are overcome.
