Metasurface-based Target Imaging and Range Detection

Abstract

In this paper, we propose a mechanism to realize target imaging and range detection based on a single digital programmable metasurface (DPM). The DPM is used to generate biphase coded signals for range detection, and random radiation patterns for target imaging. Simulations show well performances of DPM-based target imaging and range detection. This work shows great potentials of DPMs in intelligent electromagnetic sensing.
