Abstract
An air-navigational beacon, designed to simulate an imaginary circular ben with a multiplicity of pairs of diametrically opposite dipoles excited in cyclic succession, comprises an array of stationary dipole pairs disposed along lines parallel to a given direction. The spacing of the dipoles of each pair varies from one pair to another according to a sinusoidal law in their order of energization. The two dipoles of a pair are energized in relative quadrature and with a signal amplitude proportional to their spacing.
