The invention discloses a calibration method for a high-power millimeter wave intensity measurement system, which belongs to the technical field of millimeter waves. The method includes: establishing a three-dimensional Cartesian coordinate system based on the geometric center of the high-power millimeter-wave output port and the target plate; setting at least three markers in the plane where the high-power millimeter-wave output port and the target plate are located; Perform imaging; based on the imaging coordinates of the marker and the corresponding three-dimensional coordinates, coordinate transformation is used to calculate the imaging parameters from the high-power millimeter-wave output port and the target plate to the camera, and then the rotation of the high-power millimeter-wave output port to the target plate is obtained. Translation relationship: adjust the measurement system according to the rotation and translation relationship transformed from the high-power millimeter-wave output port to the target plate, and complete the system calibration. The method of the invention has low difficulty in development, high reliability and strong versatility, and can realize parameter calibration of a high-power millimeter-wave intensity measurement system and improve measurement accuracy.
Description
technical field [0001] The invention belongs to the technical field of millimeter waves, and more specifically relates to a calibration method for a high-power millimeter wave intensity measurement system. Background technique [0002] In the field of magnetic confinement controlled nuclear fusion research, there are various heating methods for plasma. Among them, high-power millimeter wave is a heating method widely used in fusion devices because of its good heating effect and good heating localization. Usually, in addition to the main mode signal, there is a certain proportion of miscellaneous mode signals in the high-power millimeter wave in the heating system. These miscellaneous mode signals are generally deposited in the system by heat, and in severe cases, it will affect the normal operation of the system. Even damage the system, so it is extremely important to analyze the mode purity information of high-power millimeter waves and further reduce the proportion of mixe...
