Motion state detectors, methods and systems based on wireless signals

摘要

PROBLEM TO BE SOLVED: To provide a device, a method and a system for detecting a motion state based on a radio signal. SOLUTION: The device calculates a change state of energy distribution of a reflection point over time based on a radio reflection signal from a space where a detection target is located, and based on the change state, a motion state of the detection target The detection process is simple, the detection results are reliable, and it can be applied to various application scenarios without the need to train the recognition model.
