High Resolution Two-Dimensional Imaging of Spinning Space Debris

摘要：

A high resolution two-dimensional imaging algorithm of spinning space debris is proposed in this paper. It incorporates the characteristic that the space debris rotates around its principal axis at a certain angular speed and it is applicable to various ldnds of signals, such as LFM signal, random noise signal. The corresponding compensation terms are constructed by searching for matched twodimensional parameters and the position information of scattering points is obtained by energy accumulation using FFT. CLEAN method is combined to enlarge target dynamic range. Imaging of spinning debris by noise frequency modulated continuous wave (FMCW) signal is taken as an example to be analyzed and simulated. The simulations confirm the validity of the proposed algorithm.
