Abstract

A system and a corresponding method for monitoring the presence of a person in a monitored area, includes a passive radiometer that detects radiation emitted from a predetermined monitored area in a predetermined frequency range between 1 GHz and 100 THz and that generates a radiation signal from the detected radiation, a radiation signal processor that processes the radiation signal and that generates, based on the processed radiation signal, a monitoring signal indicating the presence or absence of a person in the monitored area, and an application controller that controls an application based on the monitoring signal.
