Title:
アレイ・アンテナにキャリブレーションを施す方法及び装置
Document Type and Number:
Japanese Patent JP2010540894
Kind Code:
A
Abstract:
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.
