The invention relates to a closed loop-based automatic calibration method and closed loop-based automatic calibration equipment. During initial search, a method for changing the scale and narrowing the search range is adopted, the calibration efficiency of an initial calibration point is guaranteed, and the accuracy is also guaranteed; and in the process of performing multi-point calibration, a calibration value inheriting the last calibration point is adopted to estimate the search scale and search range of later calibration points, and the efficiency and accuracy of each later calibration point are guaranteed. The application range of the method and the equipment is greatly widened; and the method and the equipment can be used for calibration under various conditions such as multiple power points, multiple DATT values and the like, can be used for calibrating one-dimensional space factors and also can be used for searching and calibrating multi-dimensional space factors.
