+
+## Examples
+
+From the command-line:
+
+```
+otbcli_SARTopographicPhase -insarslave s1b-s4-slc-vv-20160929t014610-20160929t014634-002277-003d71-002.tiff -incartmeanmaster CartesianMaster.tiff -ingrid ./FineDeformation.tiff -out topographicPhase.tiff
+```
+
+From Python:
+
+```
+import otbApplication
+
+app = otbApplication.Registry.CreateApplication("SARTopographicPhase")
+
+app.SetParameterString("insarslave", "s1b-s4-slc-vv-20160929t014610-20160929t014634-002277-003d71-002.tiff")
+app.SetParameterString("incartmeanmaster", "CartesianMaster.tiff")
+app.SetParameterString("ingrid", "./FineDeformation.tiff")
+app.SetParameterString("out", "topographicPhase.tiff")
+
+app.ExecuteAndWriteOutput()
+```
