Arguments

scan

a scan (sweep) of class scan

vp

a vertical profile of class vp

quantity

profile quantity on which to base range corrections, 'eta' or 'dens'.

param

reflectivity factor scan parameter on which to base range corrections. Typically the same parameter from which animal densities are estimated for object vp. One of 'DBZH','DBZV','DBZ','TH','TV'.

lat

Geodetic latitude of the radar in degrees. If missing taken from pvol.

lon

Geodetic latitude of the radar in degrees. If missing taken from pvol.

antenna

radar antenna height. If missing taken from vp

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.

re

Earth equatorial radius in km.

rp

Earth polar radius in km.

Details

to be written

Value

an object of class 'scan'
