beam_rangeR Documentation

Calculate radar beam range

Description

Calculates the range (i.e. slant range) given a distance measured along the earth's surface (i.e. down range) and beam elevation.

Usage

beam_range(distance, elev, k = 4/3, lat = 35, re = 6378, rp = 6357)

Arguments

distance

numeric. Distance from the radar as measured along sea level (down range) in m.

elev

numeric. Beam elevation in degrees.

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

depends on beam_height to calculate beam height.

Value

numeric. Beam range (slant range) in m.

Examples

# slant range of the 5 degree elevation beam at a down range of 100 km:
beam_range(100000, 5)
