(csh-scripts)
PURPOSE
One category of csh scripts are used to read the raw data tapes
provided by a number of receiving stations. Other csh scripts
support the efficient use of the MSP. The use of scripts to
optimize the use the MSP by running several programs in an
automated sequence (guided by the script) is highly recommended.
The scripts may also be taken as an example on how to write new
scripts, matching user requirements.
NAMES AND FUNCTIONS
| script | data type | origin |
|---|---|---|
| ERS_ASF_RAW | raw | Alaska SAR Facility Raw Data |
| ERS_CCRS_RAW | raw | Canadian Centre of Remote Sensing |
| ERS_ESA_EIC | raw | ESA EIC internal format |
| ERS_ESA_RAW | raw | ESA Standard ERS format |
| ERS_UKPAF_RAW | raw | UK-PAF (ERS frame on 3 tapes, prior to 1997) |
| JERS_RAW | raw | NASDA JERS-1 raw data (multiple data sets on one tape possible, after ~1998) |
| JERS_RAW_92 |
|
NASDA JERS-1 raw data (single raw data scene on a tape 1992 -- 1998) |
If the raw data is provided in several files (older UK-PAF and CCRS data), the raw data file is generated by concatenating the individual files into one file using the UNIX command:
cat first_file.raw.1 second_file.raw.2 third_file.raw.3 > first_file.raw
These scripts perform the following functions:
1. Reading the CEOS leader files
2. Searching for missing lines (ERS)
3. Generating the processing parameter files
4. Determining the Doppler centroid across the swath
5. Radio Frequency Interference (JERS)
6. Range compression
7. Autofocus
8. Azimuth compression
9. Multilook detected image generation
They are here to be as examples for custom scripts that users will write specifically for their own applications.
| Script | Function |

| JERS_PROC | Full resolution SAR processing of JERS data in NASDA format |
| JERS_SURVEY | JERS-1 survey processing |
| RSAT_PROC | Full resolution SAR processing of RADARSAT StripMap mode data |
| SIRC_PROC | Full resolution SAR processing of SIR-C data in JPL format |
| SIRC_SURVEY | Survey processing of SIR-C data |
DIAGNOSTICS
Using the scripts without arguments provides information on the
input parameters required for a script.
