Description

technical field [0001] The invention relates to the field of environment perception positioning, in particular to an environment perception positioning system and method based on a reconfigurable intelligent reflective surface. Background technique [0002] The reconfigurable intelligent reflector system uses the ability of the metamaterial reflector to regulate wireless signals, and performs beamforming on the reflected signal, so that the signal beam is concentrated on the receiving end of the target user equipment, thereby enhancing the signal-to-noise ratio of the user equipment. . [0003] The smart reflective surface in this system is composed of reconfigurable metamaterial units arranged in a two-dimensional periodic shape. The reconfigurable metamaterial unit contains a printed circuit, a dielectric plate, and a diode. The diode connects two separate printed circuits and can The on-off state of the diode is controlled by the magnitude of the applied voltage, thereby...
