Performance Comparison of Two Recently Proposed Adaptive Differential Evolution Algorithms on Space Only Low Sidelobe Synthesis Problem of Concentric Regular Hexagonal Antenna Arrays

The problem of space only low sidelobe synthesis for concentric regular hexagonal antenna arrays (CRHAA) is considered in this work. Two recently proposed version of Differential Evolution (DE), named as Adaptive Differential Evolution (ADE) and Mutation Adaptive Mechanism based DE (EWMA–DE) which attempt to adapt its parameters on the fly are compared for this problem. Results reveal that EWMA–DE outperforms ADE.
