Mutual coupling calibration for electromagnetic vector sensor array

In superresolution direction-fingding, mutual coupling error among electromagnetic vector sensor's six component-antennas could degrade system performance obviously, so effective calibration is needed. At first, the cause for error is analyzed and a model of array mutual coupling error is established. Then matrix was transformed according to the special structure of error matrix and reduced the parameters' dimensions and the amount of calculation. At last, the simulation results demonstrated that this approach is correct and effective.
