Array shape calibration using a single multi-carrier pilot

In this paper, a novel single pilot array shape calibration algorithm is proposed for an arbitrary planar array. The method requires a single multi-carrier pilot operating at a known location with respect to the arbitrary array reference point. Typically two or more sources are required to calibrate the shape of a planar array. However, by exploiting the difference in the array response model when the source operates in the "near-far" and "far" field of the array, it is shown how this can be reduced to just one. Simulation results exhibiting the performance of the proposed method are also presented.
