| Adaptive antenna arrays, also known as smart antennas, are becoming progressively a viable alternative to larger antenna structures in a wide number of different scenarios. However, in order to take full advantage of the arrays¿ interference rejection and SNR (Signal-to-Noise Ratio) improvement capabilities, that is, in order to perform a correct signal beamforming via complex weights¿ manipulation, the antenna structure needs a precise calibration procedure. In this paper, an algorithm based on the Maximum Entropy principle and Burg spectral estimation is presented for the determination of the antenna elements¿ positions in an array with general geometry. Its performance is analyzed and compared with the CRLB (Cramér-Rao Lower Bound). | |
