Disclosed are a phase array radar system and a phase correction method thereof. According to the present invention, the phase array radar system comprises: a signal processing unit generating and outputting an input signal and a reference phase value, showing a phase difference between the input signal and an output signal, wherein the phase difference is a prerequisite difference for the output signal with the input signal; a distributor distributing the input signal applied by the signal processing unit; and a plurality of active correction receiving/transmitting modules, each of which is configured to receive the input signal applied by the distributor, amplify the input signal and change a phase of the same so as to allow the output signal to be discharged by a corresponding antenna device among a plurality of antenna devices of a phase array antenna, and correct a phase of the output signal in order to allow the phase difference between the input signal and the output signal to correspond to the reference phase value applied by the signal processing unit. The purpose of the present invention is to provide a phase array radar system, which autonomously conducts a phase correction process by receiving a reference phase signal. |
