Calibration method for smart antenna arrays

The invention relates to a correction antenna array receiving groove and transmission way method, wherein the antenna array comprises at least three antenna, and is a digital signal processor. In turn to calibrate the receiving groove, a a single antenna known amplitude and known phase's signal; the signal is received from the n-1 antenna from, thereby estimation n-1 and separation between a transmitting message each phase difference. For a new transmitting antenna a terminal two steps are the transmitting antenna is each antenna. The phase difference and they with the separation the pressure which are arranged as a separating the valve device. In turn to calibrate at least comprises three antenna, and digital signal processor and manner of the antenna array; the method comprises the steps: By a n-1 antenna known amplitude and known phase signal, and receiving the signal via the n ohm antenna, the estimated the n-1 and separation between a transmitting message's each phase difference, and a new receiving antenna a terminal two steps are the receiving antenna is an antenna, and military online leaders voltage difference and they separated by correcting to the separating device is a.
