C-Band 2×2 MIMO multi-carrier tomographic radar for complex environment volumetric imaging

Abstract : In this paper, we present a C-Band 2 ×2 MIMO Multi-Carrier Radar system that has been realised at the IETR laboratory and a new modulation technique that permits to avoid the use of switches. To validate this system, measurements have been done with two trihedral corner reflectors lying on a grass field, using our system and a VNA. We have processed the acquired data using the Back Projection Algorithm (BPA). VNA and MIMO-MCR give similar results with a vertical resolution of 0.37 m@1.6 m ground range and a vertical ambiguity of 0.74 m@1.6 m ground range. Therefore, the system is fully operational. © 2018 IEEE.
