A Rainfall Forecast Model Based on GNSS Tropospheric Parameters and BP-NN Algorithm
The occurrence of rainfall is the result of a combination of various meteorological factors. Traditional rainfall early warning models solely use Global Navigation Satellite System (GNSS)-derived Zenith Total Delay (ZTD) or Precipitable Water Vapor (PWV)

为研究高频全球导航卫星系统(GNSS)信号的P波和S波到时,本文利用2008年汶川MS8.0地震震时部分站点记录到的1 Hz高频GNSS数据,采用广义S变换将同震信号进行二维时频域平面分解,以此对P波和S波到时进行识别。本文通过调整广义S变换中的调节因子λa和p得出,当λa=1.05,p=1.05时,变换所得图像中的P波和S波到时均较为明显。结果表明,S变换在高频GNSS震相识别中效果明显,可作为GNSS地震学应用中一项有效的技术手段。
