dist_from_orbit(sr_alt, alpha, beta, r_sr_inv, re)¶
Returns range distances of SR bins (in meters) as seen from the orbit
With SR, we refer to precipitation radars based on space-born platforms such as TRMM or GPM.
- sr_alt (float) – SR orbit height in meters.
- alpha (
numpy.ndarray) – Array of local zenith angles of the SR beams with shape (nscans, nbeams).
- beta (
numpy.ndarray) – Off-Nadir scan angle with shape (nbeams).
- r_sr_inv (
numpy.ndarray) – Array of ranges from ground to SR platform of shape (nbins).
- re (float) – earth radius [m]
numpy.ndarray) – Array of shape (nbeams, nbins) of PR bin range distances from SR platform in orbit.
