摘　　要：在介绍曲靖非相干散射雷达的基本情况和工作参量的基础上,给出了雷达探测空间碎片的灵敏度,报道了2014年11月18日空间碎片探测的实验结果,与理论轨道计算值比较,目标的距离值有很好的一致性,确认了7个编目碎片,证实了利用曲靖非相干散射雷达开展空间碎片探测的可行性。经过进一步的技术革新,曲靖非相干散射雷达有望观测直径为5 cm左右的空间碎片,并通过组网等技术手段进一步扩充空间碎片和其他自然天体目标的跟踪能力。To contribute to the improvement of China＇s radar debris tracking capability and capacity, efforts have been made to make the newly built Qujing incoherent scattering radar capable of LEO debris surveillance, in addition to its standard space environment observations. Firstly, a brief introduction of the Qujing radar and its operational parameters were given, followed by the discussion of the debris tracking sensitivity. The modified radar system was operated on November 18, 2014, to experiment its debris tracking capability. The experiments show that the measured ranges agree well with external values, and this confirms the debris tracking feasibility of the Qujing radar. After the planned system upgrades, the Qujing radar is expected to track debris objects as small as 5 cm, and the tracking capability and capacity, including the natural celestial bodies, would be greatly enhanced through the networking with other radars.
