On-line Moveis of the Response of Beam-Steered Geophone Rays , by Steve Cole

The frequency response of a two-dimensional array of geophones to an incident plane wave is easy to compute. The seismic movie program provides a useful means to view the multidimensional result of such computations. Together, these techniques yield an array analysis tool that is easy to implement and use. Beam steering, used to pass energy incident on an array from a particular direction, is formulated here as a transformation of the receiver array that can be applied prior to array response computations to determine the response of beam-steered arrays.
