【摘要】 针对塔里木盆地沙漠地区提高地震资料分辨率的难度以及制约该问题的关键因素,研究、设计制作了特殊耦合地震波检测系统(SWDS),并利用匹配滤波技术,在不同区块、不同高差的沙丘与不同自然频率的常规耦合检波器接收的信号进行了严格的对比试验。试验结果表明,该项技术对提高沙漠地区地震资料分辨率是有效的。取得了明显的效果。更多还原

【Abstract】 Because it is difficult to improve the seismic data resolution of Tarim desert area and there are some pivotal factors which make a limitation to the problem, we have designed the special coupling seismic wave detect system(SWDS) which combines the research about the physical characters of earth surface in the area. And we have made some strict experimentation to contrast the signal detected by the technology of matched filtering in different areas,under different altitude differences and by different natural frequencies with detected by conventionality coupling geophones.The result shows that,the technology is very useful to improve the seismic resolution in the desert,the effect is very visible.更多还原
