Abstract : The patent describes a method for generating D.F. signals having the characteristic that their phase difference is proportional to the azimuth with respect to the radiating source. An array of four, vertical, dipole elements equiangularly spaced with respect to the center of the array is fed with a sine wave which is in phase of all the elements and, simultaneously, with another sine wave which is progressively phase-shifted in order, around the array. The sine wave carriers may be phase-modulated with orthogonally related, pseudonoise-coded signals.
