The invention discloses a target positioning turntable system capable of reducing electromagnetic interference. The system comprises a supporting main body built in a foundation pit, a central positioning shaft is mounted in the middle of the supporting main body in a penetrating manner, a photoelectric conversion device is fixedly arranged at the lower part of the central positioning shaft, the photoelectric conversion device is connected with an electrical control cabinet through a signal output cable, and the electrical control cabinet is fixed on the foundation at the lowermost part; a turntable is installed on the upper portion of the center positioning shaft, a turntable top is fixed to the upper portion of the turntable, installation bases are arranged on foundation pits on the two sides of the turntable top, and copper brushes making contact with the side faces of the turntable top are installed in the installation bases; servo motors for driving the turntable to rotate are further arranged on the two sides of the center positioning shaft, the servo motors are connected with the electric control cabinet through motor control cables, and a copper net is further buried in the foundation. According to the invention, the safety of the target positioning turntable and a tested target is ensured, the influence of electromagnetic interference on the electromagnetic environment of a shielding darkroom is eliminated, and the confidence of a test result is improved.

    本发明公开了一种降低电磁干扰的目标定位转台系统,包括建立在地基基坑内的支撑主体,支撑主体中部贯穿安装有中心定位轴,中心定位轴下部固定设置有光电转换装置,光电转换装置通过信号输出电缆与电气控制柜连接,所述电气控制柜固定在最下部的地基上;中心定位轴上部安装有转台,转台上部固定有转台台面,转台台面两侧的基坑设置有安装基座,安装基座内安装有与转台台面侧面接触的铜刷;中心定位轴两侧还设置有驱动转台转动的伺服电机,伺服电机的通过电机控制线缆与电气控制柜连接,地基内还埋设有铜网。本发明保证了目标定位转台及被测试目标的安全性,同时消除了电磁干扰对屏蔽暗室电磁环境的影响,提高测试结果的置信度。
