4.4.3 Vegetation movements
4.4.3.1 RockSpot system incorporates state-of-the-art algorithms for the correction of vegetation-induced false alarms.
However, it must be noted that modelling of real phenomena like vegetation movements leads to an approximation
of real-world physics, which may not be always effective, and could introduce false alarms, especially in densely
vegetated areas.
4.4.4 Hydrological elements
4.4.4.1 RockSpot system provides measurement in very wide area, however the presence of natural moving hydrological
elements (such as rivers, waterfalls, etc.) inside the system FoV may introduce false alarms, especially in areas where
these elements are present.
4.4.5 Machinery
4.4.5.1 RockSpot system provides measurement in very wide area, however the presence of machineries such as trucks,
shovels, etc. must be taken into account. These moving objects inside the system FoV may introduce false alarms,
especially in areas where these machineries are present.
4.4.6 Multiple reflection
4.4.6.1 Due to the complex physics of electromagnetic wave propagation some slope scenarios could generate multiple
reflections of radar waves which cannot be totally be a-priori predicted or detected. The presence of such reflections
may introduce spurious data, which could limit the detection performance of the radar. In these circumstances a
proper evaluation by radar expert may be necessary to assess the origin of the interference.
4.4.7 Multiple Survey Unit interference
4.4.7.1 RockSpot system is designed to operate with various simultaneously active sensors. However, the close presence of
multiple Survey Units, may introduce interference signals which, in some circumstances, could affect the detection
performance. To avoid this, one should not point directly one sensor in front of another, especially if the distance
between them is less than 2 km.
4.4.8 External devices interference
