Polarized Beam Online Reconfiguration Technique For Flexible Deformation Antennas
In response to the challenges posed by the deformation of flexible polarized array antennas,which results in difficulties in beam reconstruction and compromised beam performance,polarization beam online reconstruction technique based on flexible deformation polarized antennas is proposed in this paper.Firstly,the deformation state of the array is modeled based on a wing model,and real-time deformation data is obtained using modal analysis to reconstruct the antenna array model online.Secondly,the element response of vector array antenna is utilized to construct a flexible array antenna signal model in three-dimensional space.Finally,a deep integration of the Cyclic Algorithm(CA)and Second-Order Cone Programming(SOCP)is employed to solve the dynamic optimization problem of this optimal polarization beam reconstruction.Simulation results demonstrate that within a certain range of deformation and under different arc and angle requirements from environmental loads,the proposed method can achieve online antenna array reconstruction and real-time optimal polarization beam reconstruction based on the dynamic antenna array model.The directional gain,beamwidth,and polarization matching design all meet the requirements for practical engineering applications.
