High-resolution 3-D imaging of group rotating targets

This paper proposes a three-step method for high-resolution three-dimensional imaging of group rotating targets in uniform linear motion. In the first step, motion compensation is performed simultaneously with the whole target set. Then, the matched filter is designed to estimate the coordinates of scattering centers. Finally, the anisotropy of dominant scattering centers is described via phase compensation. Simulation results have proved the validity of the proposed method.
