6.7 Calculating target's size using angle readings
To calculate height and width user will need to estimate the distance to the target and measure its horizontal and vertical angles. Then using the formula for distance measurement one can calculate target’s height:
H=DxK,
where K is vertical angle in mils, D is distance in meters and
H is height in meters.
For example: if distance to the target is 0.6 km and its horizontal angle is 30 mils and its vertical angle is 60 mils, using the formula you can calculate:
The height: H=0.6 x 30= 18 m
The width: W=0.6 x 60=36 m
