Abstract In this paper a mutual coupling calibration method suitable for uniform linear arrays is presented where only one known calibration source in the near field is necessary for effective calibration, which can be extended to the case of uniform circular arrays. The paper has also discussed the position error influence of the source on the calibration., and the optimum azimuth of the source is analized. Finally some simulation results are given to show the advantages of the new method.
