利用射电望远镜与雷达构成双基地系统是一种探测 LEO 轨道空间碎片有效手段。该系统充分发挥射电望远镜探测灵敏度高的特点，提高地基监测系统的空间碎片的探测能力。对基于大口径射电望远镜构成的双基地空间碎片探测系统进行了介绍，分析了基于射电望远镜的双基地探测系统的工作频率对探测性能的影响，针对特定尺寸小碎片目标的探测距离以及在目标距离范围内系统对小碎片的探测能力分别进行了仿真实验。文中所作的研究为国内利用射电望远镜建设小碎片监测系统提供了参考。

The bi-static system based on large radio telescope is a useful approach for LEO space debris detection.It is able to enhance the capability of ground based observation system through utilizing the high sensitivity of radio telescope.We introduce the working mode of this kind of bi-static system in the present work.The relationship of operating frequency and detection capability is analyzed.The detection range of fixed RCS targets and the detection capability of small space debris at fixed range are discussed on the basis of simulation results.The present work gives a theoretical basis for the construction of space debris observation system by use of domestic large radio telescopes.
