Figure 5-3 can be used if the angle of overlapping coverage or the distance (S) between 
sensors is known:  

 

Spacing for other angles:  For units that are not coplanar (in a line) 
If the sensors are not pointing the same direction in a line, it will be necessary to reduce the 
spacing between sensors to ensure that there is no gap in coverage.  This is necessary when 
the sensors are required to go around the corner of a perimeter, or are placed along an 
irregularly shaped perimeter.  The reduction in maximum spacing is necessary to ensure 
proper coverage without significant gaps.  

 

D2 = D1*cos(

θ),   where θ = angle from boresight.
