Distance measurement
How to work the scaled graticule
for rangefinding
To measure distance by a simple formula
when height or hength is known:
Distance (in km) =
Height of target object (m)
Angular Elevation
1)
of target object
Distance (in km) =
Length of target object (m)
Azimut
2)
of target object
In practice, sizes (Height / Length) of observed
objects are known with reasonable accuracy
1)
Angular Elevation = Vertical Angle
2)
Azimut = Horizontal Angle
since they are often people, buildings and
vehicles.
