| Abstract: | In this paper,a novel blind mutual coupling self-calibration algorithm especially tailored to cross array is proposed.This method compensates for the mutual coupling not only between sensors in each subarray but also between two subarrays.Exploiting the property of coupling matrix,the proposed method requires neither the calibration sources in known locations nor the multidimensional nonlinear search.This method can jointly estimate the DOAs of the incoming signals and the unknown mutual coupling coefficien... |
