Abstract
The invention relates to a technique for millimeter-wave active image reconstruction. According to a method aspect, Tx subgroups of transmitting antennas of an antenna array are established. Coherent processing of measurement data is performed for each Tx subgroup and coherent subimages are achieved. Magnitudes of complex numbers are calculated to obtain a magnitude subimage for each of the coherent subimages and an object image is generated by adding the magnitude subimages.
