+# SARCorrelationRough
+
+Computes SAR correlation shift (rough shifts).
+
+## Description
+
+This application comutes rough shifts between two images : shift in range and shift in azimut. The inputs of this application are MultiLooked images (real images).
+
+## Parameters
+
+**Input Master image (real image)** `-inmaster image` *Mandatory* <br />
+Master Image (real image).
+
+**Input Slave image (real image)** `-inslave image` *Mandatory* <br />
+Slave Image (real image).
+
+**MultiLook factor on distance** `-mlran int` *Default value: 3* <br />
+MultiLook factor on distance.
+
+**MultiLook factor on azimut** `-mlazi int` *Default value: 3* <br />
+MultiLook factor on azimut.
+
+**rough shift in range dimension into SLC geometry (output of this application)** `-shiftranslc float` *Default value: 0* <br />
+rough shift in range into SLC geometry.
+
+**rough shift in azimut dimension into SLC geometry (output of this application)** `-shiftazislc float` *Default value: 0* <br />
+rough shift in azimut into SLC geometry .
+
+**rough shift in range dimension into ML geometry (output of this application)** `-shiftranml float` *Default value: 0* <br />
+rough shift in range into ML geometry.
+
+**rough shift in azimut dimension into ML geometry (output of this application)** `-shiftaziml float` *Default value: 0* <br />
+rough shift in azimut into ML geometry .
+
+**Available RAM (MB)** `-ram int` *Default value: 256* <br />
+Available memory for processing (in MB).
+
+## Examples
+
+From the command-line:
+
+```
+otbcli_SARCorrelationRough -inmaster s1a-s4-slc-vv-20160818t014650-20160818t014715-012648-013db1-002_ML.tiff -inslave s1b-s4-slc-vv-20160929t014610-20160929t014634-002277-003d71-002_ML.tiff
+```
+
+From Python:
+
+```
+import otbApplication
+
+app = otbApplication.Registry.CreateApplication("SARCorrelationRough")
+
+app.SetParameterString("inmaster", "s1a-s4-slc-vv-20160818t014650-20160818t014715-012648-013db1-002_ML.tiff")
+app.SetParameterString("inslave", "s1b-s4-slc-vv-20160929t014610-20160929t014634-002277-003d71-002_ML.tiff")
+
+app.ExecuteAndWriteOutput()
+```
+
+## Limitations
+
+Only Sentinel 1 products and Cosmo are supported for now.
