horizonrange
Horizon range
Syntax
Rh = horizonrange(H)
Rh = horizonrange(H,Re)
Description
Rh = horizonrange(H)H meters
above the surface. The computation uses an effective earth radius
of approximately 4/3 times the actual earth radius.
Rh = horizonrange(H,Re)
Input Arguments
|
Height of radar system above surface, in meters. This argument can be a scalar or a vector. |
|
Effective earth radius in meters. This argument must be a positive scalar. Default: |
Output Arguments
|
Horizon range in meters of radar system at altitude |

Horizon Range
The horizon range of a radar system is the distance from the radar system to the earth along a tangent. Beyond the horizon range, the radar system detects no return from the surface through a direct path.
The value of the horizon range is:
where Re is the effective earth radius and H is the altitude of the radar system.
