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.
Parameters: - 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]
Returns: ranges (
numpy.ndarray
) – Array of shape (nbeams, nbins) of PR bin range distances from SR platform in orbit.
