MECHANICAL INSTALLATION GUIDE LINES:
7.1.
Installation height:
Between 1 to 1.5 meters and above the terrain to avoid multi pass at the radar coverage area.
7.2.
ROI Observation Requirement:
180° azimuths with ± 7.5° elevation sector in front of the Radar has to be free of
objects obscuring the line of sight including cables and wires.
The Radar elevation beam shape is a 15º wide "Pencil Beam" type. This beam has 0º
squint relative to the mechanical radar elevation axis.

Two radars installation - Distance calculation
Installing two Radars for a 180
sector results in a minimal detection range in the overlapping
region between the Radars. The minimal range in the overlapping region is dependent on the
distance and angle between the Radars. The distance between the two installed Radars (for
180° coverage) is calculated as:

where d is the distance between the two units, L is the minimum detection range (blind range)
