时序激发等间隔震源组合获得指向性波束的原理与方法

PRINCIPLE AND METHOD OF FORMING THE DIRECTIONAL BEAM BY PRE-SET TIME SEQUENCE SHOT OF EQUAL INTERVAL SOURCES ARRAY

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, the author presented a new theory and method about the combination of sources by time and space. He pointed out that a narrow direction-controllable and width-controllable beam could be formed by the method mentioned above. He also analysed all the factors and their effects affected on the direction and width of the beam and indicated the possible application of this method to oil exploration.
