SIGNAL PROCESSING SYSTEM, SENSOR SYSTEM, BIOMETRIC MANAGEMENT SYSTEM, ENVIRONMENT CONTROL SYSTEM, SIGNAL PROCESSING METHOD, AND PROGRAM

The problem to be overcome by the present invention is to provide a signal processing system, a sensor system, a biometric management system, an environment control system, a signal processing method, and a program, all of which contribute to recognizing the condition of the autonomic nervous system of a person even without using a high-accuracy heartbeat sensor. A signal processing system (2) is provided with a heartbeat information acquisition unit (21), a representative value calculation unit (23), and a neural recognition unit (25). A heartbeat information acquisition unit (21) acquires heartbeat information, which is a detection result of a heartbeat of a person (H1), from a radio wave sensor (1). A representative value calculation unit (23) calculates, on the basis of the heartbeat information, a representative value of an interval of the heartbeat during a predetermined time period. A nerve recognition unit (25) recognizes a condition of the autonomic nervous system of the person (H1) on the basis of t
