Abstract
A method for detecting diaper wetness based on a ratio signal technology comprises: sending a frequency-modulated continuous wave signal to a diaper through a radar device to obtain a transmission signal S(t) and a return signal S(t); detecting a static environment factor and a dynamic environment factor, and obtaining continuous radar snapshots; eliminating interference of environmental factors by using a filtering template based on the continuous radar snapshots and object respiration; obtaining an outline of the diaper by using wavelet synchronous compression transformation, and dividing into a training sample set and a testing sample set; and inputting the training sample set and the test sample set into a heuristic mobility network for training until a loss function is converged, obtaining the trained heuristic mobility network, and obtaining diaper wetness of the test sample set.
