Fig. 1. Schematic of the intelligent target tracking system.

The RS-camera automatically detects the position of a moving target in the environment. The position information of the selected target is taken as the input of the pre-trained artificial neural network (ANN), and the coding sequence of the metasurface is output in a few milliseconds, which is sent to the dual-polarized programmable metasurface through FPGA, thus realizing smart beam tracking and wireless communications.
