| The Application of Noise Suppression Technology to Seismic Data of Antarctic Sea Area Based on LIFT |
| During China’s 33rd Antarctic Expedition, the vessel “Hai Yang Liu Hao” of Guangzhou Marine Geological Survey, which is subordinated to China Geological Survey of Ministry of Natural Resources, obtained more than 1 400 km of high resolution multichannel seismic data in the South Shetland Trench area of the Antarctic Peninsula, from December 2016 to February 2017. The main noises in the seismic data were abnormal high-energy noise and multiples. In order to suppress noises with high fidelity and fully suppress noises under the premise of maximizing the protection of effective signals, the authors designed a noise suppression method based on LIFT (Linear Interference Filter Technology). This method was used to suppress the abnormal high-energy noise and multiples respectively. The results show that the noise is well suppressed, the effective signal is well protected, and the purpose of high-fidelity denoising is achieved. |
