The method of active antenna, and refresh the amplitude and phase of the signal processing method

Embodiments of the present invention discloses an active antenna, a signal processing method and a method of refreshing the amplitude and phase, and the invention is to solve the complex structure of the phase shifting network, the problem of unreliable. The active antenna includes an antenna transducer array, the cell array transceiver, a digital processing unit, the antenna element array including antenna elements, for converting the electromagnetic wave signal and a radio frequency signal; said transceiver unit array including a transceiver letter machine unit, a transceiver unit for, when receiving a signal, the frequency demodulated signal at a radio frequency to the antenna element IQ analog signal, output to the digital processing unit; a unit for processing the digital when the reception signal, downconverts the IQ demodulated IQ analog signal into a digital signal, and the digital signal IQ digital beamforming.
