Abstract :
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.
