摘要
在Matlab平台上设计实现了一套能自动识别并修复尖峰、间断、阶跃等异常数据的软件FTsoft,提高了工作效率。通过对比FTsoft与Tsoft预处理结果发现,FTsoft与观测模拟值差值标准差比Tsoft小,进一步验证了FTsoft程序的有效性。
This paper designs an automatic preprocessing software-FTsoft,which can automatically identify the abnormal position of the gravity tide signal and design a key to correct it.It’s designed and implemented on the Matlab platform.This paper compares the results of Tsoft preprocessing and of FTsoft preprocessing in preprocessing the gravity tide.It proves that the standard deviation of the differences between the FTsoft processing result and the simulated theory gravity tide is smaller than that of Tsoft FTsoft preprocessing software can be used to automaticly preprocess the gravity tide observations.
