Abstract: A signal processing system includes a heartbeat information acquisition unit, a representative value calculation unit, and a nerve recognition unit. The heartbeat information acquisition unit acquires, from a radio wave sensor, heartbeat information as a result of detection of a person's heartbeat. The representative value calculation unit calculates, based on the heartbeat information, a representative value of an interval of the heartbeat during a predetermined period. The nerve recognition unit recognizes, based on the representative value, a condition of the person's autonomic nervous system.
