High Resolution 3D Microwave Real Time Imaging System Based on Intelligent Metasurface

In this paper, we present a high-resolution 3D microwave real time imaging system based on intelligent metasurface that can acquire richer information of the human body efficiently without cooperation and process the data in real time. The imaging system is based on a convolutional neural network (CNN) architecture that can process the microwave data instantly. Our evaluation results show that 3D microwave imaging system tracks each key point on the human body with an average error of 4cm. The reported 3D microwave imaging system could open a new avenue for smart homes, human-device interaction interfaces and healthcare.
