Abstract

 The article presents a method for compensating for amplitude and phase deviation among channels in phased-array radar receivers with digital beamforming. The digital distorter for amplitude and phase mismatch compensation is designed based on digitized signals to be suitable for practical implementation in FPGA chip. The architecture of the digital distorter performs calculations of nonlinear inverse characteristic among channels. Adaptive algorithms for adjusting the characteristics of the digital distorter are also presented. Simulation results of the distorter design using Matlab software are provided to demonstrate the effectiveness of the proposed method.
