中文摘要：
对于尺寸小于雷达距离分辨率的太空碎片进行雷达成像，以前提出的方法只有SRDI（Single Range Doppler Interferometry）。该文针对太空碎片运动特点，给出了一种单距离匹配滤波太空碎片成像方法。该方法利用一个距离单元横向回波数据经不同旋转半径参考信号匹配滤波后得到太空碎片二维像。仿真结果表明这种方法比LSRDI方法计算量少、成像效果好。
英文摘要：
For space debris radar imaging with the dimension smaller than radar range resolution, only Single Range Doppler Interferometry （SRDI） is discussed before. Considering movement features of space debris, a Single Range Matching Filtering （SRMF） approach for space debris radar imaging is proposed in this paper. The proposed approach is to obtain 2-D image of space debris by using a range unit cross-range echo data and by matching filtering the signals with different turning radius. Simulation results show that of the proposed approach, its computational load is less than that of SRDI, and its imaging effect is better.
