Method for calibrating the transmission of phased array antenna with built-in local oscillator and electronic device

An electronic device, comprising:

• a processor;
• a memory coupled to the processor;
• and
• a computer program stored in the memory and configured to be executed by the processor, wherein the processor, when executing the computer program, is configured to perform a method for calibrating a transmission of a phased array antenna, wherein the method comprises:
• constructing and configuring a test system, wherein a receiving antenna is located on a central axis of the phased array antenna, and the receiving antenna is connected with a spectrum analyzer;
• dividing the phased array antenna according to a layout of the phased array antenna, wherein the layout of the phased array antenna is divided into a plurality of centrally symmetric ring areas according to the central axis of the phased array antenna, and each of the ring areas comprise one or more centrally symmetric sub-units, and each of the sub-units comprises a same number of antenna channels;
• and
• transmitting signals using the phased array antenna and receiving signals by the receiving antenna, and performing amplitude and phase calibration between the antenna channels within the sub-units of the ring areas, between the sub-units of the ring areas, and between the ring areas.
