| Abstract: | This paper gave a brief review of recent situation in processing geophysical signals home and abroad. It covered extracting weak geophysical signals on strong nisc backgroud, processing of nonstationary geophysical signal, development of modern spectral estimation, application of temporal spectral theory in geophysical signal processing, the recovering of distorted signal, and concerning problems about signal processing. |
