PATTERN SYNTHESIS OF THE CIRCULAR ARRAY IN TRANSMITTING MODE

Circular array (CA) – an array of elements the corresponding points of which lie on a circle. The creation of the theory of phase excitation [1-5] made it possible to apply for CA the well-known methods of synthesis of directional pattern (DP) and reduction of the side-lobe level (SLL) developed for linear arrays (LA). Investigations of the beamforming algorithms for single-ring CA base on the application of the phase excitation theory provisions. It indicates on the existing differences in the formation of the DP in the modes on receiving and transmitting [1, 3, 4, 6].
