摘　　要：遥测信号的数据处理品质直接影响对飞行试验结果的分析与评定。在研究HHT方法的基础上,结合遥测信号的特征,将HHT应用于遥测信号数据的趋势项提取与排除和滤波降噪中,并与传统的遥测信号处理方法进行对比分析。实测数据分析结果表明,基于HHT的遥测信号分析处理方法更准确、有效。The quality of data processing for telemetry signals directly determines the analysis and assessment of flight test re- sults. Based on the research on HHT technology and combined with the characteristic of telemetry signals, HHT is used in the trend extraction and elimination, and de-nosing and filtering of telemetry signals. Analysis results of test data show that compared with the traditional method, the method of telemetry signal processing based on HHT technology is more accurate and more effective.
