Improving Beam Granularity Performance of Reconfigurable Refelctarray Radars via Spatial Quantization and Phase Quantization Approach
Year: 2025
Type: preprint
Abstract: In this paper, the impacts of spatial quantization and phase quantization on the beam granularity characteristic of reconfigurable reflectarray (RRA) radars are systematically investigated. From the perspective of the difference beam, a theoretical analysis is conducted to derive the factors influencing beam granularity. To validate the theoretical findings, simulations are performed under various quantization scenarios: specifically, 1-bit, 2-bit, and 3-bit spatial quantization with 1-bit phase quantization, as well as 1-bit, 2-bit, and 3-bit phase quantization with 1-bit spatial quantization. The experimental results demonstrate that both spatial quantization and phase quantization effectively reduce beam granularity in reconfigurable reflectarray radars, thereby enhancing the angular resolution of the beam. These findings offer valuable insights and practical reference for beam-tracking applications in radar and communications.
