| Popis: | In this paper, a ring array imaging method for near-filed security screening is proposed for densely populated areas security imaging. With the fixed transceivers, this method can avoid the motion phase error, which is ineluctable in traditional synthetic aperture radar (SAR). Besides, the number of transceivers is less than planar array radar with the same quality of imaging results. The convolution back propagate (CBP) algorithm is adopted to reconstruct image to avoid the phase error, which is created by plane-wave hypothesis for near-field imaging in high-frequency band. Moreover, the simulation results of CBP and other imaging algorithm are described and compared. And the experimental results are shown to verify the performance of this method. |
