Summary:The invention discloses an antenna measurement system. The antenna measurement system comprises a signal processing device; the signal processing device is connected with a transmitting link; the transmitting link is connected with the input port of a coupler; the first output port of the coupler is connected with a transmitting antenna; the second output port of the coupler is connected with the first changeover port of a changeover switch; the second changeover port of the changeover switch is connected with a receiving antenna; the common port of the changeover switch is connected with a receiving link; and the receiving link is connected with the signal processing device. The present invention also provides a method of eliminating factors influencing the stability of the antenna measurement system. The method comprises the steps of determining reference probe signals, determining sampling signals and determining test signals. Since radio frequency power link loss and temperature noises in the reference pr
