The application discloses a kind of intelligent reflecting surface assisted computational imaging method, it is related to
wireless communication field.
System is composed of multiple single antenna
terminal equipment, an intelligent reflecting surface comprising several reflecting units and a multi-antenna
base station, while there is an object to be imaged.
Base station adjusts the
reflection coefficient of intelligent reflecting surface with the criterion of minimizing the
mean square error of imaging.All
terminal equipment simultaneously emits sensing
signal to the object to be imaged in environment, part of
signal reaches
base station after scattering through the object to be imaged and reflecting by intelligent reflecting surface, another part of
signal reaches
base station directly after scattering through the object to be imaged, and base
station uses best linear unbiased estimator to realize the imaging of scatterer.The application provides an
effective method for intelligent reflecting surface assisted
wireless computational imaging of three-dimensional object.
