seismic arraysA diverse group of more than 70 seismologists met for 2 days in Raleigh, N.C., to report on recent innovations in seismic array methods and to discuss the future of seismic arrays in global seismology. The workshop was sponsored by the Incorporated Research Institutions for ...
a planar phased array is sufficient to effectively shape wave beams in a 3-Dimensional (3D) space; an in-line arrangement is capable of the same in a 2D space. As such, phased arrays and their underlying operational principles are
The resulting hyperbeam is obtained by subtraction of sum and difference beams, each raised to the power of the exponent u. Figure 1 Open in figure viewerPowerPoint Sum beam pattern for the 10-element linear array for u = 1. Figure 2 Open in figure viewerPowerPoint Difference beam ...
