摘要

本文介绍了一种通过控制反射波的相位来诱导人工多普勒效应的方法。此外，我们还使用了具有2位时变相位的时调制超表面来实现该方法。在此基础上，提出了一种典型运动目标微多普勒特征曲线的拟合方法。最后给出了仿真结果，验证了该方法的正确性。

Artificial Doppler and Micro-Doppler Effect Induced by Time-modulated Metasurface

In this contribution, an approach of inducing artificial Doppler effect by controlling the phase of the reflected wave is introduced. Furthermore, we used a time-modulated metasurface which has 2-bit time varying phase to realize this approach. On this basis, a method of fitting the micro-Doppler characteristic curve of a typical moving target is proposed. Finally, the simulation results are given to verify the correctness of the method.
