本文提出一个按时间与空间组合震源的新的理论和方法,它可以给出一个指向与束宽可控的较狭窄的波束.研究了各种因素对所形成的波束的指向与束宽的影响.给出了这种波束勘探理论可能的应用前景.
In this paper, we propose a new theory and method of combining seismic sources in time and space, which can provide a narrower beam with controllable and narrower beam widths.The effects of various factors on the beam pointing and beamwidth are studied The potential applications of this beam exploration theory are given.
