摘要
Embodiments of channel parameters consistency calibration methods in multi-channel phased array systems are disclosed. The method comprises a reference channel calibration step and a calibration step for other channels to be calibrated. The reference channel calibration step comprises selecting one channel as a reference channel and performing a full state calibration on the reference channel to generate full state control data set S(A). Parameters to be calibrated in the calibration step of the uncalibrated channel may be a phase shift amount or an attenuation amount. The calibration step for the uncalibrated channel comprises a calibration under at least one specified parameter group. Compared with the conventional calibration methods, the present calibration method greatly shortens the calibration time, reduces the required data storage capacity, thereby improves efficiency for completing the consistence calibration of the parameters for multi-channel phased array systems.
