Normalized altitudinal pattern of radiated energy as a function of altitude at a given distance from the radar.
gaussian_beam_profile( height, range, elev, antenna = 0, beam_angle = 1, k = 4/3, lat = 35, re = 6378, rp = 6357 )
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. |
numeric.
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)
