Efficient phase-only linear array synthesis including mutual coupling and platform effect

The least-square active element pattern expansion (LS-AEPE) has been introduced for linear array synthesis including mutual coupling and platform effect. A new method based on combination of LS-AEPE and iterative Fourier transform (IFT) is proposed to optimize the excitation phases for sidelobe reduction and null control. Simulation results illustrate the new method outperforms the GA-FFT method base on LS-AEPE in terms of computational efficiency.
