Synthesis of Integrated Radiation Patterns for Radome-Enclosed Phased Arrays based on ADMM

The presence of radomes causes pattern distribution in phased array, such as introducing boresight error and sidelobe level degradation. To address it, this paper proposes an integrated pattern optimization method for radome-enclosed phased arrays. The proposed method fully accounts for mutual coupling effects among the array and the radome. The short-circuited active element pattern (SC-AEP) is obtained by VSIE-MSI-MFLMA and used to synthesis the total system patter. Excitations can be optimized by using ADMM. Numerical results demonstrate that this optimization method provides an effective and practical solution.
