ANSI-C program: base_orbit.c
NAME
base_orbit - computes interferometric baseline from ERS state
vectors given in the SLC parameter files of the interferometric
pair.
SYNOPSIS
base_orbit <SLC1_par> <SLC2_par>
<baseline_file>
| <SLC1_par> | parameter file for reference SLC-1 |
| <SLC2_par> | parameter file for SLC-2 |
| <baseline_file> | baseline file (text format, enter - for none) |
EXAMPLE
base_orbit 1352.par 1610.par 1352_1610.base
DESCRIPTION
base_orbit reads state vectors in SLC parameter files, computes
interferometric baselines and generates baseline parameter file.
The baseline parameter file is used for the removal of the
average phase trend of the interferogram and for the computation
of the heights. The baseline is estimated as the vector between
the tracks when the second track passes through the Doppler cone
of the reference track. No output baseline file is written if "-"
is specified.
OPTIONS
The interferogram fringe rate can be used to estimate the
perpendicular baseline component using base_est_fft, or in combination with
offsets and orbit information using base_init.
