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. (6 pages)
