NAME

par_<facility> - creates SLC Parameter File from CEOS Leader files or similar annotation (e.g. xml file) for a number of SAR sensors as provided with the SLC or PRI data by different receiving stations / processing facilities, or from the Gamma MSP Processing Parameter File.

par_<facility> reads the original data file(s), searches for information needed for ISP SLC/MLI image  parameter file, and creates the ISP SLC/MLI image  parameter file. If needed, it reformats the image data to adhere to the format of the GAMMA software.

DESCRIPTION:
The ISP has a standard parameter file format to describe SLC and multi-look intensity image products. In this way data from many different processors can be used by the ISP.  For processed SLC or ground range data, a CEOS format leader file or an annotated file is provided by the processing facility. In a few cases the annotation is stored in the same file as the image data (e.g. ENVISAT ASAR). Parameters from these files can be extracted, and the necessary calculations performed to generate the ISP image parameter file.

For data processed through the MSP, the MSP processing parameter and sensor parameter files  provide the necessary information.

In the case of  data processed from RADARSAT-1 and RISAT-1, the image needs to reformatted and possibly flipped in range or in the along-track direction such that the direction of range and azimuth time is always increasing for processing with the Gamma software.

Sentinel-1 TOPS mode SLC data consist of a set of bursts (nominally 10) in a single SLC. Since there are 3 Swaths in Interferometric Wide mode (IW), there are 3 SLC images saved as TIFF format images in each image data set. These have names like s1a-iw1-slc-vv-20140809t165546-20140809t165611-001866-001c20-004.tiff. The data are short complex (16 bit real, 16 imaginary), but are converted to float complex (32-bit real, 32-bit imaginary) after scaling by the program par_S1_TOPS.c The output of par_S1_SLC are a binary float complex image, the SLC parameter file and a Burst parameter file called the TOPS_par. See TOPS_par documentation.
