A Flexible Hemispherical Coverage Array Antenna Based on Multi-Planar Arrays

A flexible hemispherical coverage array antenna based on multi-planar arrays is proposed to meet the growing demands for multi-target TT&C. The advantages and disadvantages of multi-planar arrays and dome phased in engineering implement are compared. Meanwhile, the influence of different number of plane arrays on antenna pattern is analyzed. For the purpose of interference suppression a novel beamforming method by adding constraint conditions is analyzed to enhance the performance of antenna for TT&C system. System simulation is done based on the multi-planar arrays antenna. The feasibility of hemispherical coverage and the performance of anti-jamming are verified. Finally, a comprehensive summary is given.
