    • 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.
    • 本发明涉及一种用于校准阵列天线的方法,包括通过使用分配给某个分支的伪随机序列来生成测试信号,将生成的测试信号加到阵列的不同分支中,从而产生一个有用的信号, 通过阵列天线发射的相加信号,用接收机天线接收相加的信号,将接收到的加和信号与与用于产生测试信号的那些相同的伪随机序列的副本相关,估计 通过处理相关结果来分支,并且基于估计的特性来校准天线。
