1. System for monitoring the presence of a person in a monitored area comprising:
- 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 said radiation signal and that generates, based on said processed radiation signal, a monitoring signal indicating the presence or absence of a person in said monitored area, andan application controller that controls an application based on said monitoring signal.

Abstract
The present invention relates to a system and a corresponding method for monitoring the presence of a person in a monitored area. To reliably monitor the presence of the person, the system comprises:
- 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 said radiation signal and that generates, based on said processed radiation signal, a monitoring signal indicating the presence or absence of a person in said monitored area, and
- an application controller that controls an application based on said monitoring signal.

12. Method for monitoring the presence of a person in a monitored area, comprising the steps of:
-
detecting radiation emitted from a predetermined monitored area in a predetermined frequency range between 1 GHz and 100 THz, generating a radiation signal from the detected radiation, processing said radiation signal and generating, based on said processed radiation signal, a monitoring signal indicating the presence or absence of a person in said monitored area, and controlling an application based on said monitoring signal.
