| Abstract: | Two-dimensional scattering distribution imaging approaches in near-field measurement are studied in the paper. Continuous-wave flat plane scanning method is proposed to get the coronal imaging. The acceptance signal is decomposed to a set of plan wave, which radiate in all directions. The phase of each wave is shifted according to its spreading angle so as to recover the original field on the coronal region, and synthesized together to reconstruct the scattering distribution. Computer simulation results show that the algorithm is effective and correct. |
