# make\_s1a\_tops(1)

make\_s1a\_tops

## NAME

make\_s1a\_tops - make\_s1a\_tops

## SYNOPSIS

**make\_slc\_s1a\_tops** *xml\_file tiff\_file output mode dr.grd da.grd*

## DESCRIPTION

This program is part of GMTSAR.

- xml\_file

  \- name of xml file

- tiff\_file

  \- name of tiff file

- output

  \- stem name of output files .PRM, .LED, .SLC

- mode

  \- (0) no SLC; (1) center SLC; (2) high SLCH and lowSLCL; (3) output ramp phase

- dr.grd

  \- range shift table to be read in

- da.grd

  \- azimuth shift table to be read in

Example: make\_slc\_s1a\_tops s1a-s1-slc-vv-20140807.xml s1a-s1-slc-vv-20140807.tiff S1A20140807 1 dr.grd da.grd

-

  make\_slc\_s1a\_tops s1a-s1-slc-vv-20140807.xml s1a-s1-slc-vv-20140807.tiff S1A20140807 1

Output: mode 1: S1A20140807.PRM S1A20140807.LED S1A20140807.SLC

-

  mode 2: S1A20140807.PRM S1A20140807.LED S1A20140807.SLCH S1A20140807.SLCL S1A20140807.BB

Note: if dr and da are not given, SLCs will be written with no shifts.

-

  s1a-aux.xml and manifest.safe(exclude the first line) should be concatenated to the xml\_file for

-

  acquisitions acquired before Mar 2015 (IPF version change). If not concatenated or IPF version is 2.43+,

-

  elevation antenna pattern correction(EAP) will not be applied
