ABSTRACT:
A method and apparatus are provided for operating a microwave detector for detecting intruders within a secured area. The method includes the steps of selecting a noise floor based upon a setting of a range setting potentiometer, detecting a magnitude of a signal reflected from a test subject within the secured area that exceeds the selected noise floor and establishing a threshold value for detecting an intruder based upon the magnitude of the detected signal and sensor mounting height.
