NAME

       ALOS_pre_process - ALOS_pre_process

SYNOPSIS

       ALOS_pre_process imagefile LEDfile [-near near_range] [-radius RE] [-swap] [-V] [-debug] [-quiet]

DESCRIPTION

       This program is part of GMTSAR.

       creates data.raw and writes out parameters (PRM format) to stdout

       imagefile        ALOS Level 1.0 complex file (CEOS format): LEDfile         ALOS Level 1.0 LED file (CEOS
       leaderfile format):

              options:

       -near near_range        specify the near_range (m) -radius RE              specify the local earth radius
       (m) -swap                   do byte-swap (should be automatic) -nodopp                 does not calculate
       doppler  (sets  fd1  to  zero!)   -npatch                 set  the  number   of   patches   -fd1   [DOPP]
       sets  doppler  centroid  [fd1]  to DOPP -quad                  adjust parameters for quad pol mod (PRF/2)
       -ALOSE                  use  ERSDAC  format  -ALOS                   use  AUIG  format   (default)   -LED
       write  GMTSAR  generic  LED  format  output  and update PRM (default) -noLED                 do not write
       GMTSAR  generic   LED   format   output   -roi                     write   roi_pac   format   output   -V
       verbose    write    information)    -debug                    write    even   more   information   -quiet
       don't write any information -force_slope chirp_slope       force a value for the chirp  slope  -chirp_ext
       chirp_ext              force   a   value   for   the   chirp   extension   (integer)   -tbias       tbias
       correct    the    clock    bias    (positive    value    means    plus)     Example:     ALOS_pre_process
