Effective DoF Collapse in Sparse Near-Field Beamforming: A Block-Rank-1 Mechanism
Sparse near-field arrays phase-cohere $M$ widely separated sub-arrays of $N$ elements and underpin distributed MIMO, satellite formations, and integrated sensing and communication. We show that their interference suppression over a protected region is set by coherence within a single sub-array rathe
