Abstract: The present disclosure provides a signal processing method and apparatus. The method includes: extracting the chest cavity movement signal from the radar echoes, which are the electromagnetic signals reflected from the target; extracting the respiratory signal and heartbeat signal by performing the bandpass filters on the chest cavity movement signal, wherein the respiratory signal corresponds to a respiratory bandpass frequency of the filter, and the heartbeat signal corresponds to a heartbeat bandpass frequency of the filter; performing joint time-frequency analysis on the respiratory signal to obtain a respiratory frequency, and performing joint time-frequency analysis and statistical analysis on the heartbeat signal to obtain the heartbeat frequency corresponding to the heartbeat signal.

Abstract: The application discloses a method and device for detecting information of an object in a room, a storage medium and a processor. The method comprises the following steps: collecting target information of a target object in the room by target detection equipment, wherein the target information at least comprises vital sign information and behavior information of the target object, and the target detection equipment comprises radar monitoring equipment that the target object do not need to wear and vital sign monitoring equipment that the target object wears; analyzing behavior state information of the target object based on the target information; and displaying the behavior state information of the target object on a display interface. Through the application, the problem of poor information detection effect on indoor personnel in related technologies is solved.
