Novel radar angle reference automatic calibrator

The invention discloses a novel radar angle reference automatic calibrator, which comprises a stepping motor, a pitch rotation mechanism connected with the stepping motor via a coupler, an azimuth rotation mechanism, a rotation hinge, a U-type support, a polarization rotation motor, a signal collector body, a horn receiving port and a scale base, wherein the front end of the signal collector body is provided with the horn receiving port; the left end and the right end of the rotation shaft of the pitch rotation mechanism are inserted in the U-type support of the calibrator base; the rotation hinge is arranged on the scale base and is connected with the stepping motor via a gear; a remote control terminal at a radar antenna end carries out three-dimensional motion control on the receiving horn port of the calibrator in a wireless data transmission mode, the data measured at the horn port are wirelessly back transmitted to the radar antenna end, and the data are displayed at the remote control terminal.
