The embodiment of the invention relates to a radar technology, and discloses a calibration system and method, a radar chip, an integrated circuit, a radio device and terminal equipment. The system comprises a plurality of target simulators arranged in a far field of a radar to be calibrated and a rotary table used for bearing and driving the radar to be calibrated to rotate around a zero-degree angle, and the rotary table enables the radar to be calibrated to obtain at least two groups of calibration data from different echo directions through the plurality of target simulators; wherein the plurality of target simulators are distributed in different range gates of the radar to be calibrated, and/or the speeds of the targets simulated by the plurality of target simulators are distributed in different speed gates of the radar to be calibrated. According to the method, the data volume sufficient to support the azimuth pitching joint calibration can be obtained through fewer rotation times, and operations such as
