Abstract: A signal processing method is executed by a signal processing device connected to a radio device that transmits radio waves in given periods and receives reflection waves, to process signals of the reflection waves. The signal processing method includes: obtaining positional information on a moving object at respective times based on the signals of the reflection waves; identifying a coordinate that is a coordinate in an axis in a transmission direction of the radio waves, and satisfies an end condition of a gesture from among the obtained positional information at the respective times; and extracting a group of consecutive coordinates including the identified coordinate as an end point.

Abstract: An information processing apparatus includes a calculation unit configured to calculate distance spectra based on a beat signal being a difference between a transmitted wave, which is a radio wave that is transmitted by a sensor and that is swept in frequency, and a reflected wave of the transmitted wave, the reflected wave being received by the sensor, and configured to calculate one or more time-sequenced waveforms each indicating time changes in intensity of the distance spectra with respect to respective distances from the sensor, and a detection unit configured to detect respiration of a living organism based on the one or more time-sequenced waveforms.
