Single Range Matching Filtering Based Space Debris Radar Image

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.
