SARDeramp

Deramping/Reramping of S1 IW Burst.

Description

This application does the deramping or reramping of S1 Iw burst.

This application has several output images and supports “multi-writing”. Instead of computing and writing each image independently, the streamed image blocks are written in a synchronous way for each output. The output images will be computed strip by strip, using the available RAM to compute the strip size, and a user defined streaming mode can be specified using the streaming extended filenames (type, mode and value). Note that multi-writing can be disabled using the multi-write extended filename option: &multiwrite=false, in this case the output images will be written one by one. Note that multi-writing is not supported for MPI writers.

Parameters

Input burst -in image Mandatory
Input burst (from S1 Iw product).

Input SAR slave image (for interferometry processing -inslave image
Slave SAR Image to extract SAR geometry (interferometry).

Output burst -out image [dtype] Mandatory
Output burst (deramped or reramped).

Input deformation grid -ingrid image
Input deformation grid.

Grid Step for range dimension into SLC geometry -gridsteprange int Default value: 150
Grid Step for range dimension into SLC geometry.

Grid Step for azimut dimension into SLC geometry -gridstepazimut int Default value: 150
Grid Step for azimut dimension into SLC geometry.

Activate Reramping mode -reramp bool Default value: false
If true, then reramping else deramping.

Activate Shift mode (To reramp/deramp accordingly a deformation grid) -shift bool Default value: false
If true, reramp/deramp accordingly a deformation grid (interferometry processing).

Available RAM (MB) -ram int Default value: 256
Available memory for processing (in MB).

Examples

From the command-line:

otbcli_SARDeramp -in s1b-s4-slc-vv-20160929t014610-20160929t014634-002277-003d71-002.tiff -out s1a-s4-slc-vv-20160818t014650-20160818t014715-012648-013db1-002_Deramp.tiff

From Python:

import otbApplication

app = otbApplication.Registry.CreateApplication("SARDeramp")

app.SetParameterString("in", "s1b-s4-slc-vv-20160929t014610-20160929t014634-002277-003d71-002.tiff")
app.SetParameterString("out", "s1a-s4-slc-vv-20160818t014650-20160818t014715-012648-013db1-002_Deramp.tiff")

app.ExecuteAndWriteOutput()

Limitations

Only Sentinel 1 (IW and StripMap mode) and Cosmo products are supported for now.
