Analysis of the Influence of Subarray Beamforming on Frequency-Hopping Communication System

Frequency-hopping phased array system has the advantages of flexible and variable beam, strong multi-beam capability, anti-interference, and anti-intercept, but its front-end beamforming will consume more hardware and software resources. This paper proposes a simplified subarray-level digital beamforming strategy for resource-limited frequency-hopping phased array system. The influence of the simplified strategy on the performance of frequency-hopping signals is analyzed and simulated, which has certain guiding significance for the actual system design.
