10.1 Introduction to barriers - MW microwave section
These barriers are characterised by a 24GHz electromagnetic wave emitted by a transmitter that
generates a cigar-shaped zone, until it reaches its receiver, so you are always in the presence of a pair
of columns, the width of which in the centre reaches up to 4-5m.The most peripheral part is called the
SENSITIVE ZONE while the most central part is called the ALARM ZONE

Signal interruption:ALARM
When a body approaches longitudinally until it crosses the lobe, the signal received by the
receiving section is perturbed until an alarm is generated.
Attenuation can be large or small depending on the mass and type of material that crosses the
emission zone.
