A novel method on radar 3-D imaging

To realize perception to local lunar surface under the condition of relative stationary before soft landing during moon discovery, a novel 3-D imaging method is proposed. The method is based on receiving digital beamforming and modulated frequency stepped radar signal processing. The outstanding feature is this method can realize 3-D imaging without relative motion between radar and target. Simulation results indicate that it can obtain coordinates of strong scattering centers accurately and reconstruct 3-D image of scene successfully.
