Abstract
A height measurement device and a height measurement method based on a millimeter-wave radar are provided. The height measurement device comprises a millimeter-wave radar module, a main controller, and a wake-up module. The wake-up module and the millimeter-wave radar module are connected to the main controller, respectively. The wake-up module activates the millimeter-wave radar module through the main controller. The millimeter-wave radar module sends a transmission signal and receives an echo signal, and obtains an intermediate-frequency signal based on the transmission signal and the echo signal. The echo signal is formed by the reflected back transmission signal after it encounters human head. The main controller applies continuous millimeter waves to sweep across the highest point of the human head and obtain height data based on the intermediate-frequency signal. When height measurement is needed, the wake-up module activates the millimeter-wave radar module, achieving non-contact, high-precision height measurement and reducing energy consumption.
