Abstract
Embodiments of this disclosure provide a motion state detection apparatus and method based on wireless signals and a system, in which variations of energy distribution of reflection points with time are calculated according to wireless signals reflected from a space where an object that is detected is located, and a motion state of the object is determined according to the variations. Thus, the training of the recognition model is not needed, the detection process is simple and detection results are reliable, and are applicable to various different application scenarios.
