The invention relates to the technical field of target electromagnetic scattering characteristic testing, in particular to a gantry crane of a target electromagnetic scattering characteristic testing field. The gantry crane comprises a bridge, a frame, a rotating unit, a sling beam, a connecting beam and a lifting unit, the lifting unit is fixed to the frame through the rotating unit, the sling beam is fixedly connected with the rotating unit through the connecting beam, and the frame is movably fixed to the bridge. The frame can drive the rotating unit, the sling beam, the connecting beam and the lifting unit to move in the direction of the cross beam of the bridge frame, the rotating unit can drive a measured target to rotate by a required angle, and the distance between the lifting points is adjusted by adjusting the distance between the two first pulleys arranged in the sling beam. Compared with the prior art, the whole structure is simpler and more reasonable, the target test result cannot be affected, and extra hoisting weight cannot be occupied.

    本发明涉及目标电磁散射特性的测试技术领域,尤其涉及一种目标电磁散射特性测试场的龙门吊架。该龙门吊架包括桥架、车架、旋转单元、吊具梁、连接梁和升降单元,升降单元通过旋转单元固定在车架,吊具梁通过连接梁与旋转单元固定连接,车架可移动地固定在桥架,使车架能够带动旋转单元、吊具梁、连接梁和升降单元沿桥架的横梁方向移动,旋转单元能够带动被测目标旋转所需角度,通过调节设置在吊具梁内的两个第一滑轮之间的距离,实现吊点间距的调整。相比现有技术中,整个结构更为简单合理,且不会影响目标测试结果,也不会占用额外的吊装重量。
