Claim Text:
1. A method for detecting and repairing a channel anomaly of an active antenna, comprising: determining an operation state of a transmission channel or a reception channel by analyzing in real time data of a feedback coupling channel or data of the reception channel, if the operation state is anomalous, performing an anomaly protection and reporting an alarm; determining a level of the alarm and a reason causing the alarm, if data of the transmission/reception channel are anomalous and the anomaly protection is performed, storing a current antenna beam forming parameter and setting the antenna beam forming parameter to zero; after the alarm has been eliminated, setting a stored valid antenna beam forming parameter to a valid value; and if a transmission/reception analog channel operates anomalously and the anomaly protection is performed, re-acquiring the antenna beam forming parameter and configuring an acquired valid antenna beam forming parameter.
