The invention relates to a method for calibrating an array antenna, comprising generating a test signal by using a pseudo-random sequence assigned to a certain branch, adding the generated test signals in the different branches of the array to a useful signal, which leads to a summed signal to be emitted via the array antenna, receiving the summed signal with a receiver antenna, correlating the received summed signal with a replica of the pseudo-random sequence identical to this used for the generation of the test signal, estimating the characteristics of the branch by processing the correlation result, and calibrating the antenna based on the estimated characteristics. |
