ABSTRACT:
A microwave detection system includes a transmitter configured to transmit a signal along a path to detect an intruder to a monitored zone and a modulating reflector configured to receive the transmitted signal to generate a modulated signal having a characteristic introduced by said modulating reflector, the modulating reflector being configured to transmit the modulated signal. The system also includes a receiver located to receive the modulated signal and an adaptive threshold adjustment unit configured for providing a variable detection threshold responsive to a change in a gain of the system. The system further includes a processor configured for processing the modulated signal provided by the receiver and configured for measuring a characteristic in the processed modulated signal with respect to the variable detection threshold provided by the adaptive threshold adjustment unit.
