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 …
