Reverse time migration for reconstructing extended obstacles in planar acoustic waveguides被引量：2
《Science China Mathematics》2015年第9期1811-1834,共24页CHEN ZhiMing HUANG GuangHui 
supported by National Key Basic Research Program of China(973 Program)(Grant No.2011CB309700);National Natural Science Foundation of China(Grant Nos.11021101 and11321061)
We propose a new reverse time migration method for reconstructing extended obstacles in the planar waveguide using acoustic waves at a fixed frequency. We prove the resolution of the reconstruction method in terms of ...

Application of sparse time-frequency decomposition to seismic data被引量：3
《Applied Geophysics》2014年第4期447-458,510,共13页王雄文 王华忠 
funded by the National Basic Research Program of China(973 Program)(No.2011 CB201002);the National Natural Science Foundation of China(No.41374117);the great and special projects(2011ZX05005–005-008HZ and 2011ZX05006-002)
The Gabor and S transforms are frequently used in time-frequency decomposition methods. Constrained by the uncertainty principle, both transforms produce low-resolution time-frequency decomposition results in the time...

Analysis of geophone properties effects for land seismic data
《Applied Geophysics》2009年第1期93-101,104,共10页李桂林 陈高 钟俊义 
supported by the National Basic Research Program of China(973 Program)(Grant No.2007CB209603)
The properties of the seismic geophones are important factors for high-resolution seismic exploration and have a great influence on data quality. For this reason, we have tested three kinds of geophones currently used...
