IV. Results
The acquisition of information for current development status of infrasound analysis system(PMCC, Matseis, Inframonitor) will be done through the case research, the adoptation strategy is proposed for KMA functionality. The classification of infrasound parameter is done. The method for volcano and artificial earthquake monitoring is proposed with KMA’s infrasound recordings and related infrasound data recording institute with recording data sharing. The analysis technique for the KMA’s infrasound monitoring with array network to adopt F-k method or PMCC method was proposed.
Several technique for signal processing was reviewed and proposed for the infrasound data control and the flow of signal process program was proposed. After signal processing technique adoption to the recordings of infrasound, the adoption process was proposed.
The infrasound pathway study was done by case study and the classification for the transfer parameter for the infrasound.
1^st years research product was adopted for the construction of KMA’s infrasound analysis system.
At the stage of 2^nd years period, constructed KMA’s infrasound analysis system was analysed for the advanced function propose. Related infrasound analysis software case study results was list-up for support advanced function development.
The data processing for the continuous recording of KMA’s 2012 infrasound recording was manipulated. The recordings qualification was done by compare analysis with support of removable infrasound station recordings. The MATLAB code development for the PDS, FFT, Peridogram representation, wavelet transformation was done for frequency characteristic analysis. The correlation of typhoon of 2012’s with recordings was done, and the changing characteristic by typhoon contact in Korean peninsula was confirmed.
The proposed method for current stage of KMA’s infrasound infrastructure advance was listed by succeeded to get the fine construction blue-print of IMS station. Through this high potential findings, advanced lightening protection technique and changing composion of the sensor and the recording station.
The MATLAB code manipulation for cross-correlation, wavelet transform, automated frequency characteristic report generate algorithm, peridogram with long term continuous recordings.
