Aiming at problem that mutual coupling effect of electromagnetic vector sensor array cause degradation of system performance

study a kind of distributed electromagnetic vector sensor array mutual coupling calibration algorithm based on opportunity. Firstly

analyze linear array from performances such as signal to noise ratio

direction of arrival estimation precision and number of extended aperture dimension

mathematical model for structure characteristics of triangular array and double triangle array; and then according to result of performance analysis

construct electromagnetic vector sensor opportunity type array architecture; finally

put forward opportunity type mutual coupling calibration algorithm suitable for distributed electromagnetic vector sensor array.Experimental results prove that the proposed distributed electromagnetic vector sensor opportunity type array mutual coupling calibration algorithm has obvious advantages than the static sensor array in direction of arrival estimation precision

spatial spectrum estimation precision and signal-to-noise ratio.
