Process for accurate radar cross-section evaluation using reconfigurable intelligent surfaces

Abstract

A radar cross-section (RCS) measurement system comprising a reconfigurable intelligent surface (RIS) transceiver positioned relative to a first illumination direction of a target under test (TUT), a RIS reflector positioned relative to a second illumination direction of the TUT, and a controller. The controller is configured to control the RIS transceiver to transmit an electromagnetic (EM) wave towards the first illumination direction of the TUT and the RIS reflector, control the RIS reflector to reflect the EM wave received from the RIS transceiver towards the second illumination direction of the TUT, control the RIS reflector to reflect a scattering of the EM wave received from the second illumination direction of the TUT back to the RIS transceiver, and compute the RCS of the TUT in the second illumination direction of the TUT based on the scattering of the EM wave received from the RIS reflector.
