Abstract
System and method for correcting a phase noise generated by vibration of an antenna transmitting or receiving a radio frequency (RF) signal in a signal propagation direction includes: measuring the vibration of the antenna by a sensor generating an output signal; converting the output signal of the sensor to a measurement signal proportional to the vibration of the antenna in the signal propagation direction; performing a single or double integral of the measurement signal to produce a control signal with an amplitude proportional to the vibrational velocity or displacement of the antenna in the signal propagation direction; and applying the control signal to an oscillator, a clock signal, or a phase controller associated with the RF signal.
