Abstract
A phase calibration method for a phased array antenna is provided. The method includes: sequentially calibrating M×N antenna units based on a pre-obtained test voltage set including first test voltages; sequentially loading the first test voltages to the antenna unit in the ith row and the jth column, and acquiring phase and amplitude information of a microwave signal radiated by the antenna unit every time one first test voltage is loaded; acquiring first array vectors through analysis based on the phase and amplitude information of the acquired microwave signals of the antenna unit under different first test voltages; obtaining a calibration response vector of the antenna unit under each first test voltage in the test voltage set through a first preset algorithm based on the first array vector, and determining a target voltage-phase curve corresponding to the antenna unit in the ith row and the jth column.
