Abstract

See full text

The invention relates to a MIMO imaging radar system. The system comprises transmission channels (Ve1, VeM), reception channels (Vr1, VrN), and co-located radiating elements (ERe1, EReM, ERr1, ERrN) forming a two-dimensional antenna array. Each radiating element (ERe1, EReM, ERr1, ERrN) has a predefined instantaneous field of coverage. Each radiating element is formed by a plurality of p radiating sub-elements (SeElt1, SsEltp) distributed in at least one of the two dimensions of the antenna array. The radar comprises a plurality of electronic steering modules (MDe1, . . . , MDrN). Each electronic steering module is connected to one radiating element. Each steering module is configured to apply a steering command (Cmd) between all the radiating sub-elements (SeElt1, SsEltp) of a given radiating element. The steering command (Cmd) is identical from one radiating element to the next, so as to move the field of coverage of each radiating element in the same direction.
