Synthesis of Phase-Only Reconfigurable Linear Arrays Using Multiobjective Invasive Weed Optimization Based on Decomposition

الملخص EN

Synthesis of phase-only reconfigurable array aims at finding a common amplitude distribution and different phase distributions for the array to form different patterns.

In this paper, the synthesis problem is formulated as a multiobjective optimization problem and solved by a new proposed algorithm MOEA/D-IWO.

First, novel strategies are introduced in invasive weed optimization (IWO) to make original IWO fit for solving multiobjective optimization problems; then, the modified IWO is integrated into the framework of the recently well proved competitive multiobjective optimization algorithm MOEA/D to form a new competitive MOEA/D-IWO algorithm.

At last, two sets of experiments are carried out to illustrate the effectiveness of MOEA/D-IWO.

In addition, MOEA/D-IWO is compared with MOEA/D-DE, a new version of MOEA/D.

The comparing results show the superiority of MOEA/D-IWO and indicate its potential for solving the antenna array synthesis problems.
