【摘要】@@ A seismic array is a set of seismographs being arranged in a regular geometric pattern to improve signalto-noise ratio (SNR).Seismic arrays at various length scales have been introduced since early 1960s and have been proved to be superior to single three-component stations for detecting and characterizing signals from earthquakes and explosions.The better detection capability of arrays is achieved with a so-called \technique, which suppress noises
while
preserving
signals,
thus
enhancing
SNR.The
\technique also estimates the wave vector, i.e., backazimuth and apparent velocity of an incoming signal, which is crucial in identifying the signal, e.g., whether it is a P, S, local, regional or teleseismic wave. 【总页数】2页(1-2) 【关键词】
