Abstract: Disclosed herein is a method (600) for an image reconstruction. The method comprises capturing (602) data from a plurality of Multiple Input Multiple Output Synthetic Aperture Radar (MIMO-SAR) millimetre (mm) wave sensors scanning an object at two or more offset points. The two or more offset points correspond to placement of the MIMO-SAR mm wave sensors at different locations relative to the object. The method comprises reducing (604) size of the captured data by pre- processing the captured data at the two or more offset points in frequency domain. The method comprises obtaining (606) a two-dimensional image from the captured data of reduced size for each of the two or more offset points using back-projection. The method comprises reconstructing (608) the image of the object by correlating the obtained two-dimensional images. The reconstructed image is a three-dimensional image of the object.
