基于小波相关性的对流层延迟改正数据分析

Tropospheric delay data analysis based on wavelet correlation

针对信号的非平稳性,根据小波相关性在分析两列信号相互关系方面的有效性,结合山东地壳运动GPS观测网络部分监测站的数据,利用GAMIT软件解算CASH、JIMO、RIZH、WUDI的对流层延迟改正.结果表明:两两站间的相关延迟量比较接近,没有出现较大的浮动,最小相关延迟发生在CASH-RIZH之间,最大相关延迟发生在RIZH-JIMO之间.

For the non-stationary of signal, according to the effectiveness of wavelet correlation on the analysis of the relationship between two signals, combining the data of Shandong crustal movement GPS observation network base station,the paper firstly resolved the troposphere delay of CASH,JIMO,RIZH,WUDI using GAMIT. The results show that the troposphere delay of two base stations is close. The smallest troposphere delay happens on CASH-RIZH and the biggest happens on RIZH-JIMO.
