+
+Compensated complex into master geometry between two SAR images.
+
+## Description
+
+This application estimates the compensated complex into ground geometry between two SAR images.
+
+## Parameters
+
+**Input SAR Slave image (Coregistrated image)** `-insarslave image` *Mandatory* <br />
+Input SAR Slave image (Coregistrated image).
+
+**Input SAR Master image** `-insarmaster image` *Mandatory* <br />
+Input SAR Master image.
+
+**Input Topographic Phase (estimation with DEM projection)** `-topographicphase image` <br />
+Input Topographic Phase (estimation with DEM projection).
+
+**Compensated complex image in master geometry** `-out image [dtype]` *Mandatory* <br />
+Output Image : Compensated complex image in master geometry.
+
+**Available RAM (MB)** `-ram int` *Default value: 256* <br />
+Available memory for processing (in MB).
+
+## Examples
+
+From the command-line:
+
+```
+otbcli_SARCompensatedComplex -insarslave s1b-s4-slc-vv-20160929t014610-20160929t014634-002277-003d71-002.tiff -insarmaster s1a-s4-slc-vv-20160818t014650-20160818t014715-012648-013db1-002_SLC.tiff -topographicphase TopographicPhase.tiff -out s1b-s1a-s4-CompensatedComplex.tiff
+```
+
+From Python:
+
+```
+import otbApplication
+
+app = otbApplication.Registry.CreateApplication("SARCompensatedComplex")
+
+app.SetParameterString("insarslave", "s1b-s4-slc-vv-20160929t014610-20160929t014634-002277-003d71-002.tiff")
+app.SetParameterString("insarmaster", "s1a-s4-slc-vv-20160818t014650-20160818t014715-012648-013db1-002_SLC.tiff")
+app.SetParameterString("topographicphase", "TopographicPhase.tiff")
+app.SetParameterString("out", "s1b-s1a-s4-CompensatedComplex.tiff")
+
+app.ExecuteAndWriteOutput()
+```
+
+## Limitations
+
+Only Sentinel 1 (StripMap mode) and Cosmo products are supported for now.
