Automatic calibration synthesis method and system for converting directional antenna into omnidirectional antenna

The invention discloses an automatic calibration synthesis method and system for converting a directional antenna into an omnidirectional antenna, and the method comprises the following steps: S1, configuring a device which is a transceiver processing all-in-one machine; s2, selecting a 0-degree channel and a 180-degree channel for transmitting, and respectively selecting a 90-degree antenna and a 270-degree antenna for receiving to obtain a relative phase pha180 of the 180-degree antenna; s3, selecting 0-degree, 180-degree and 270-degree channels for transmitting, and receiving by a 90-degree antenna to obtain a relative phase pha270 of the 270-degree antenna; s4, transmitting by selecting 0-degree, 180-degree and 90-degree channels, receiving by a 270-degree antenna, and obtaining a relative phase pha90 of the 90-degree antenna; and S5, respectively writing the pha90, the pha180 and the pha270 into corresponding channel phase registers, writing the 0-degree phase register into 0, and completing calibration.
