Abstract

The task of the antenna array radiation pattern optical control for ultra-wideband radio emission is considered in the paper. A fiber-optic phasing scheme is proposed, which is part of a complex fiber-optic device. The control device layout and the radio-photon segment layout photos are presented. An analytical model of the optical phasing process is developed that provides the frequency bands number calculation. The number of bands, on which a wide frequency range should be divided, depends on the permissible level of the array radiation pattern distortion. The results of experimental approbation of the radio lobe phasing control in the frequency band of 200 MHz, divided into 3 subbands of 70 MHz, are presented.
