This invention discloses a real-time online calibration system and method for a vector antenna tuner. The system includes a debugging terminal communicatively connected to the vector antenna tuner. The vector antenna tuner is equipped with a detection device, which includes a temperature sensor module, a DDS control module, a DDS measurement module, a switching module, and an OSL calibration module, all communicatively connected in sequence. In the method, the debugging terminal sends a calibration command to the DDS control module, or the temperature sensor module detects low-temperature environment information and sends it to the DDS control module. The DDS control module automatically triggers the calibration command, controls the switching module to switch states, and simultaneously controls the OSL calibration module to perform calibration in the corresponding state. This achieves real-time online automatic calibration of the antenna tuner, eliminating the need to repeatedly open and close the device and plug and unplug calibration components. It solves the problem of inaccurate impedance measurement caused by deviations in the original room-temperature calibration data due to component parameter drift in low-temperature environments, thus improving reliability and saving manpower and resources.
