Adds expected eta to a scan

Description

Adds expected eta to a scan

Usage

add_expected_eta_to_scan(
  scan,
  vp,
  quantity = "dens",
  param = "DBZH",
  lat,
  lon,
  antenna,
  beam_angle = 1,
  k = 4/3,
  re = 6378,
  rp = 6357
)

Arguments

scan

a scan (sweep) of class scan

vp

A vp object

quantity

Character. Profile quantity on which to base range corrections, either eta or dens.

param

reflectivity Character. Scan parameter on which to base range corrections. Typically the same parameter from which animal densities are estimated in vp. Either DBZH, DBZV, DBZ, TH, or TV.

lat

Latitude of the radar, in degrees. If missing taken from pvol.

lon

Latitude of the radar, in degrees. If missing taken from pvol.

antenna

Numeric. Radar antenna height, in m. Default to antenna height in vp.

beam_angle

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

k

Numeric. Standard refraction coefficient.

re

Numeric. Earth equatorial radius, in km.

rp

Numeric. Earth polar radius, in km.

Value

A scan object.
