This is because in order to better understand the physical and chemical processes, one needs to know the detailed information contained in the signals. In this thesis, three signal analysis tools, adaptive periodogram technique (APT), Morlet wavelet transform (MWT), and adaptive windowed Fourier transform (AWFT), are analyzed and their advantages and disadvantage are compared. Among them, APT is a most recently developed method in Miami University, and it uses adaptive search technique over the whole signal to detect the time and frequency information. All three methods are then applied to the analysis of gravity waves using experimental data taken by the Arecibo Incoherent Scatter Radar (ISR). The thesis presents physical interpretation based on the analysis and results. Out analysis and testing using experimental data suggest that APT shows the best overall performance. On the other hand, MWT and AWFT are computationally more efficient. By using APT, MWT, and AWFT in a complimentary manner, one can expect better performance than using any single one method. 2006-04-19 English text Miami University / OhioLINK http://rave.ohiolink.edu/etdc/view?acc_num=miami1145385180 http://rave.ohiolink.edu/etdc/view?acc_num=miami1145385180 unrestricted This thesis or dissertation is protected by copyright: all rights reserved.
