Space debris radar imaging

For space debris radar imaging with the dimension smaller than radar range resolution, only SRDI (Single Range Doppler Interferometry) was discussed before. A single range matching filtering 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 cell to transversely echo data and matching filter the signals with different turning radius. Investigations and simulations show that: of the proposed approach, its computational burden is less than that of SRDI, and its imaging effect is better.
