Supporting rotary table for microwave anechoic chamber measurement

The invention discloses a supporting rotary table for microwave anechoic chamber measurement. The supporting rotary table comprises a yawing movement mechanism, a pitching movement mechanism and a rolling movement mechanism. The pitching movement mechanism is fixedly installed on the yaw movement mechanism so that the yaw movement mechanism can drive the pitching movement mechanism to rotate in the circumferential direction. The transverse rolling movement mechanism is arranged on the pitching movement mechanism, so that the pitching movement mechanism drives the transverse rolling movement mechanism to reciprocate towards or away from the yawing movement mechanism, and the transverse rolling movement mechanism is used for driving the measured target to rotate around the axial direction of the measured target. According to the supporting rotary table for microwave anechoic chamber measurement, high-precision uniform-speed rotation of a measured target in the yaw direction can be achieved, and high-precision p
