Abstract
A passive detector () includes a receiver () configured to collect passive radiation () in an environment, where detailed information about a portion of the passive radiation is estimated as a baseline of the passive energy. The passive energy is generated by a passive source unrelated to the detector. A monitor () is configured to measure a fluctuation in the baseline. A decision module () is coupled to the monitor to determine whether the fluctuation represents a presence or motion in the environment. Detection methods are also disclosed.
