The present disclosure provides a method and device for detecting and repairing a channel anomaly of an active antenna, and the method includes: an operation state of a transmission channel or a reception channel is determined by analyzing in real time data of a feedback coupling channel or data of the reception channel, if the operation state is anomalous, an anomaly protection is performed and an alarm is reported; a level of the alarm and a reason causing the alarm are determined, if data of the transmission/reception channel are anomalous and the anomaly protection is performed, a current antenna beam forming parameter is stored and the antenna beam forming parameter is set to zero; after the alarm has been eliminated, a stored valid antenna beam forming parameter is set to a valid value; and if a transmission/reception analog channel operates anomalously and the anomaly protection is performed, the antenna beam forming parameter is re-acquired and an acquired valid antenna beam forming parameter is configured. The present disclosure can detect states of multiple transmission/reception channels of an active antenna without an extra calibration channel, thus reducing the design cost of a system. |
