Arguments

height

numeric. Height in meter.

range

numeric. Slant range in m, the length of the skywave path between target and the radar antenna.

elev

numeric. Beam elevation in degrees.

antenna

numeric. Height of the center of the radar antenna in meters

beam_angle

numeric. Beam opening angle in degrees, typically the angle between the half-power (-3 dB) points of the main lobe

k

Standard refraction coefficient.

lat

Geodetic latitude of the radar in degrees.

re

Earth equatorial radius in km.

rp

Earth polar radius in km.

Details

Beam profile is calculated using beam_height and beam_width. height and antenna should be given in reference to the same reference plane (e.g. ground level or sea level)

Value

numeric.
