o The propagation of electromagnetic signals generated by the radar, is affected by
atmospheric conditions along the travel path. IDS GeoRadar Radar technology
incorporates state-of-the-art algorithms for the correction of those atmospheric-
induced variations. However, modeling of real phenomena (like atmospheric
variations) always leads to an approximation of real-world physics, which in some
circumstances may introduce spurious data, thus limiting the radar performance.
o Due to the complex physics of electromagnetic wave propagation some slope scenarios
could generate multiple reflections of radar waves which cannot be totally predicted or
detected. In these circumstances a proper evaluation by radar expert may be
necessary to assess the origin of the interference. Furthermore, the proper alarming
on impending slope failures relies on the selection of hazard thresholds, which must
be done by skilled and properly trained operators. The selection of the thresholds is
solely an User’s responsibility and must be based on geotechnical considerations, risk
evaluation, in-situ operational procedures and, possibly, on the past records of the
slope’s movement. As such, the procedure is not inherently able to predict new,
unprecedented movement behaviors that could happen in the future and that can
result in missing alarms. Therefore, when Monitoring Products are used in critical
monitoring for safety purposes, like real time monitoring of unstable slopes, User must
be aware that the the assessment of the stability conditions of the observed targets
must be tasked to skilled and certified operator/s able to understand data supplied by
either Monitoring Products or other equipment employed to such purpose; only
operators officially trained and regularly updated by IDS GeoRadar S.r.l. (holding an
“User Certificate” thereof) are allowed to use Monitoring Products. IDS GeoRadar S.r.l.
