+
+Deramping/Reramping of S1 IW Burst and TSX mono-burst.
+
+## Description
+
+This application does the deramping or reramping of S1 Iw burst and TSX mono-burst.
+
+## Parameters
+
+**Input burst** `-in image` *Mandatory* <br />
+Input burst (from S1 Iw or TSX product).
+
+**Input SAR slave image (for interferometry processing** `-inslave image` *Mandatory* <br />
+Slave SAR Image to extract SAR geometry (interferometry).
+
+**Output burst** `-out image [dtype]` *Mandatory* <br />
+Output burst (deramped or reramped).
+
+**Input deformation grid** `-ingrid image` *Mandatory* <br />
+Input deformation grid.
+
+**Grid Step for range dimension into SLC geometry** `-gridsteprange int` *Default value: 150* <br />
+Grid Step for range dimension into  SLC geometry.
+
+**Grid Step for azimut dimension into SLC geometry** `-gridstepazimut int` *Default value: 150* <br />
+Grid Step for azimut dimension into  SLC geometry.
+
+**Activate Reramping mode** `-reramp bool` *Default value: false* <br />
+If true, then reramping else deramping.
+
+**Activate Shift mode (To reramp/deramp accordingly a deformation grid)** `-shift bool` *Default value: false* <br />
+If true, reramp/deramp accordingly a deformation grid (interferometry processing).
+
+**Available RAM (MB)** `-ram int` *Default value: 256* <br />
+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), TSX and Cosmo products are supported for now.
