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)
Azimuth
2)
of target object
1)
Angular Elevation = Vertical Angle
2)
Azimuth = Horizontal Angle
