the effects from mutual coupling and imbalance between channels on the interferometric correlation are analyzed.It is shown that the correlation error is mainly introduced by the phase imbalance.The phase balance of the central frequency can ensure the accuracy of the correlation phase
and the residual phase error will only reduce the coherency.Coherent/Incoherent noise calibration can correct the channel imbalance related interferometric correlation errors.
