ANSI-C programs: par_KC_PALSAR_slr.c
NAME
par_KC_PALSAR_slr - reads KC PALSAR data file and related
parameter files as provided by JAXA EORC and creates the data
file and ISP SLC/MLI parameter file in the format used by GAMMA
software. In Wide-Beam mode, the along-track doppler polynomials
can be converted to the Gamma geometrical model and written to a
text file.

EXAMPLES
par_KC_PALSAR_slr facter_m.dat LED_ALPSR 20070101.mli.par HH 1 sar.Q16_64_HH 20070101.mliReads the PALSAR KC parameter file facter_m.dat, the leader file LED-ALPSR, the image data file sar.Q16_64_HH (Fine Beam Single mode) and writes the ISP SLC/MLI parameter file 20070101.mli.par and the corresponding data file expressed as SAR intensity, 20070101.mli
par_KC_PALSAR_slr facter_m.dat LED_ALPSR 20070401.mli.par HH 3 sar_Q16.dat_HH 20070401.mli 20070401.fdtabReads the PALSAR KC parameter files facter_m.dat, the leader file LED-ALPSR and the image data file sar_Q16.dat_HH (Wide Beam mode) and writes the ISP SLC/MLI parameter file 20070101.mli.par and the corresponding data file expressed as SAR intensity, 20070101.mli. The doppler centroid data are converted from the JAXA model to the Gamma model and written out to the fdtab file.
DESCRIPTION
Reads PALSAR KC parameter files and data file as provided by JAXA
EORC and creates the ISP SLC/MLI parameter file in the format
used by GAMMA software. The ISP/MLI parameter file describes the
image provided by JAXA EORC. This program also generates a new
data file that expresses the KC data as SAR intensity. KC
data strips are provided in little endian, short integer and
amplitude format. The program supports the conversion of the KC
data strip to SAR intensity. The program supports KC PALSAR
images in slant range format. In the case of Wide-Beam data
(mode=3) the along-track and cross-track doppler information
provided in the facter_m.dat file can be converted to the Gamma
geometrical reference model and written to the file fdtab. This file can then be
ingested as input by the DIFF&GEO program gc_map_fd. This program has the
capability to use the doppler information stored in a table
rather than using the doppler polynomials in the image parameter
file. This approach is useful when the doppler changes are not
well modelled using a low order polynomial.
The program requires information on the polarization of the
image and the acquisition mode. For FBD images the program must
be run for each single image.
To radiometrically calibrate the image (only absolute calibration
is needed) a correction factor of -83 dB has to be applied. The
radiometric calibration is supported by the program radcal_MLI.
Below an example is given for the KC PALSAR image called sar.Q16_64_HH:
