1.4. Operation principle
1.4.1. The sensor is a bistatic microwave device.
The sensor principle of operation is to generate an electromagnetic field between Tx
and Rx. This field forms a volumetric detection zone in the form of a long ellipsoid of
rotation. The sensor registers changes of the field when an intruder crosses a protected area.
1.4.2. An intruder crossing the detection zone causes some changes of the signal
amplitude in Rx. The signal passes through the amplifier and is compared with the thresholds
value according to the algorithm. If the signal change on Rx input is provoked by a person
passage, then Rx generates an alarm, breaking actuating relay contacts. The signal changes
