Method and apparatus for controlling array antenna |
摘要 |
<p>A method of controlling an array antenna having a plurality of antenna elements for providing antenna output signals by receiving TDMA burst signals. The method includes a step of estimating a DOA of incident signal based upon the antenna output signals, a step of calculating weights with reference to the estimated DOA, a step of multiplying the antenna output signals by the calculated weights, respectively, and a step of summing the multiplied antenna output signals. The estimating step includes a first step of calculating a phase difference between the output signals of the two antenna elements during burst, a second step of calculating a phase difference between the output signals of the two antenna elements during an interval of bursts, and a third step of calculating a difference between the calculated phase differences. <IMAGE></p> |
