Cell Confidence<br />
Calculation Example<br />
•Range awareness is interpolated from the<br />
sensor per<strong>for</strong>mance range curve<br />
•Age awareness is calculated given a nominal<br />
target speed and cell mobility factor<br />
•Line of sight is calculated from ray-tracing<br />
from sensor location<br />
•Footprint percentage is calculated from<br />
polygon intersection<br />
•Terrain visibility is taken from the terrain<br />
visibility table<br />
