Abstract
- A new technique based on the multiple measurement vectors FOCal Underdetermined System Solver (M-FOCUSS) for synthesis of pattern reconfigurable sparse arrays is presented. The method, based on the MMVs sparse recovery theory, is used for finding the common element positions and individual element excitations for multiple patterns in the guidance of collaborative synthesis strategy. A reasonable tradeoff between the number of active antenna elements and pattern characteristics can be achieved. Numerical examples show the high efficiency and robustness of the proposed method. Furthermore, the M-FOCUSS method is combined with the active element pattern technique so that the mutual coupling between real antennas can be taken into account in the synthesis process. The M-FOCUSS-Active algorithm is used to design an E-plane coupled microstrip antenna array. Measured results validate the effectiveness of this approach. [ABSTRACT FROM PUBLISHER]
