The Equivalent Phased Receiver Array and Its Application in Processing of Acoustic Logging Waveforms

Che Xiaohua, Qiao Wenxiao.  
For linear phased array emitter, if appropriate delay times of sources are exerted on elements of phased array, the direction of acoustic beam radiated from the array can be steered so that the propagating energy radiated from each element is maximum in certain direction. According to reciprocity principle, when adjusting the delay time of neighboring element of a receiver array and stacking the shifting signals of different elements, the received stacking energy can also be maximal in certain direction when waveforms satisfy in-phase stacking. This paper adopts the above idea to process the acoustic full waveforms with the anticipated results.
