Abstract: | Aiming at the demand of multi-target management in aerospace, a hemispherical conformal antenna array based on fullerene structure is designed. The principle of transmit-receive signal processing in digital beamforming and the scheme of array structure designing is introduced. The operation modes of beam walking, simultaneous muti-beam and beam enhancement are studied. The mathematical model of the hemispherical conformal antenna array is established. Simulation results of beam consistence, muti-beam pattern and beam enhancement show the excellent performance of the antenna array. |
