Abstract
Channel equalization is essential in wideband digital array radar to compensate the channel distortion and mismatch. Inverse Fourier transform (IFT) method and weighted least squares (WLS) algorithm are used to calculate the coefficients of the equalizer filter. However, the accuracy of equalizer coefficient calculation is affected by many non-ideal factors in the actual correction of large-scale digital TR channels. This paper aims to analyze the influence of various non-ideal factors in equalizer coefficient calculation and propose a test method to reduce or eliminate their influence. Finally, based on 90 channel scale FPGA-based system, the method proposed in this paper is tested and verified, and good performance is achieved.
