Abstract Basing on subspace principal, this paper provides a calibration approach for mutual coupling among sensors. The benefit of this new method is that calibration signals and unknown signals can be received simultaneously, during the course of calibration. The computer simulation results demonstrate that this approach can be used for uniformly spaced linear or circular arrays and direction-finding of coherent signals.
