Blind Gradient-Ascent Phase Alignment for Multi-Aperture Coherent Digital Combining Under Aperture-Dependent Phase Disturbance
Cheng Chen, Tong Luo, Jiayin Xue +5
The paper introduces a blind gradient‑ascent algorithm that iteratively adjusts per‑aperture phase corrections to maximize the combined output power in multi‑aperture free‑space op…
