Extended Beamforming by Restored Phase Information of Virtual Array Input Signal
2021
We propose a beamforming and signal demodulation method for the development of two-dimensional (2D) array antennas. The authors have studied an extended beamforming method by using Khatri-Rao (KR) product, however it corresponds only to real-valued signals like BPSK. In this paper, we aim at improving the extended beamforming performance by recovering phase information in demodulation scheme. The performance of the proposed method is evaluated through computer simulation.
