Abstract
Methods for the construction of and controlled phase marine source arrays provide phase control for source array pulses radiated into emergence (or incidence) angles of interest. Phase control means that the phase spectra associated with source array pulses radiated in a generally downgoing direction, (i.e. for angles of emergence from the array that are of interest) will match the phase spectrum associated with a vertically downgoing source array pulse out to the 'ghost-notch' frequency associated with the vertically downgoing pulse. Although the range of emergence angles over which phase control is possible may be limited by the array geometry, proper attention to and control of array geometry and the radiation characteristics of the individual array source elements provide such controlled phase marine arrays.
