Phased array device and calibration method therefor

摘要

The calibration method, performed on a phased array device including channel elements coupled in parallel by a transmission line, has the steps of: obtaining channel responses corresponding to the channel elements through the transmission line, and each of the channel responses is obtained when one of the channel elements is turned on, and the rest of the channel elements are turned off; calculating a characteristic value corresponding to the transmission line based on the obtained channel responses of the channel elements; and adjusting a channel parameter of one of the channel elements based on the characteristic value of the transmission line.

1. A calibration method, performed on a phased array device comprising a plurality of channel elements coupled in parallel by a transmission line, the method comprising:
obtaining a plurality of channel responses corresponding to the channel elements through the transmission line, wherein each of the channel responses is obtained when one of the channel elements is turned on, and the rest of the channel elements are turned off; calculating a characteristic value corresponding to the transmission line based on the obtained channel responses of the channel elements, wherein calculating the characteristic value comprises:
obtaining a plurality of characteristic differences between the channel responses; anddetermining the characteristic value corresponding to the transmission line by the characteristic differences; and adjusting a channel parameter of one of the channel elements based on the characteristic value of the transmission line.
