Abstract: With the rapid development of 5G technology, more and more attention has been attracted to mmWave sensing. As an emerging sensing medium, mmWave has the advantages of both high sensitivity and precision. Different from its networking applications, the core method of mmWave sensing is to analyze the reflected signal changes containing the relevant information of different surrounding environments. In this paper, we conduct a systemic review for mmWave sensing. We first summarize the prior works on environmental sensing with different signal analysis methods. Then, we classify and discuss the work of sensing humans, including their behavior and gestures. Finally, we discuss and put forward more possibilities of mmWave human perception.
