Optimization of Low‐Sidelobe Beam Broadening for Spaceborne Large‐Scale Phased Arrays Based on Subarray‐Adaptive Improved JADE Algorithm

Year: 2026

Type: article

Abstract: ABSTRACT This letter proposes an improved scheme for low‐sidelobe beam broadening of spaceborne large‐scale phased arrays, addressing the efficiency and performance limitations of typical algorithms in synergistically achieving controllable beamwidth, low sidelobe suppression and high solution robustness. By integrating a dynamic subarray partitioning mechanism into crossover and mutation operations and optimizing the fitness function with a robustness constraint term, the scheme enhances optimization capability. Comparative experiments under varied beam pointing directions confirm the scheme's effectiveness: the SA‐JADE algorithm stably meets beam broadening targets with excellent sidelobe suppression and solution robustness, offering reliable technical support for spaceborne phased array applications.
