DIGITAL ANALYSIS USING FUZZY LOGICFBM
ERMO482X pro monitors the signal, comparing it with behaviour models using algorithms based on “fuzzy” logic (fuzzy behaviour models – fbm) to decide if the signal was created by a real intruder or some other factor. The size, shape and rate of change of the signal are continuously measured and compared with typical stored signals. The sensor is able to detect intruders walking, running, crawling or rolling. every event that generates an alarm or a significant change in the received signal is date/time stamped and stored in ram memory and can be analysed in real time and/or later.

FUZZY SIDE TARGET DISCRIMINATION – F.S.T.D.
For long range (over 50m) using a parabolic antenna will give a much purer signal than devices using elliptical or planar antennas. In particular situations where there is continuous interference at the side of the field, such as loose, moving metallic fences in the beam pattern, vegetation that encroaches the side of the beam or other large parallel side movements it is possible to use the FSTD function in the software. Using this it is possible to adjust the sensitivity only at the side of the beam pattern, or even exclude all signal analysis from the sides. In this way we can have a beam that although it is physically as normal, it appears elliptical with different shapes dependent on the fstd setting while maintaining the purity of signal that is the advantage of the parabolic antenna compared to an elliptical antenna.

DYNAMIC DIGITALANTI-MASKING
The 16 crystal controlled modulation channels, together with a dynamic analysis of the absolute value of the received signal, detected during the installation process, make masking impossible and possible the detection of potential faults in the microwave components.

AUTOMATIC ENVIRONMENT ADJUSTMENT
The temperature is continuously checked to detect possible faults as well as monitoring the temperature gradient (temperature change over a period of time) to compensate for signal differences created by environmental changes.
IMMUNITY TO INTERFERENCE
The ERMO 482X PRO is not affected by interference from airport radars, or from environments where there are powerful military radars. The actual evidence of this can be seen from the many installations using CIAS microwaves in civil and military airports. ERMO 482X PRO operates in the x-band which gives improved volumetric protection and less waste of space for crossing and overlap than those using the k-band.
PARABOLIC ANTENNA WITH LINEAR POLARIZATION
The parabolic antenna of the ermo barriers uses linear polarisation. this allows the head to be rotated through 90° to avoid sources of interference. antennas with circular polarisation achieve nothing if rotated in this way. Furthermore, linear polarisation has the advantage that the received signal is clearer than that received with circular polarisation. circular polarisation is good for long range data transmission but not as good as linear, in relation to signal purity, for intruder detection purposes. Different shapes dependent on the fstd setting. This maintains the purity of signal that is the advantage of the parabolic antenna compared to an elliptical antenna.
