Abstract

This paper introduces a fast imaging algorithm oriented for linear MIMO array configurations. The image reconstruction process is performed in the frequency-wavenumber domain and requires a modified interpolation process among both transmit and receive apertures. The proposed algorithm corrects completely the range curvature in the near-field and is able to provide high quality images for short-range targets. The proposed algorithm is tested by numerical simulation and further compared with Stolt migration where antenna positions are approximated by phase centers between bi-static transceiver pairs. The results demonstrate its high accuracy and computational efficiency for near-field MIMO array imaging.
