+## Examples
+
+From the command-line:
+
+```
+otbcli_SARInterferogram -insarslave s1b-s4-slc-vv-20160929t014610-20160929t014634-002277-003d71-002.tiff -insarmaster s1a-s4-slc-vv-20160818t014650-20160818t014715-012648-013db1-002_SLC.tiff -indem S21E055.hgt -mlran 3 -mlazi 3 -gain 0.1 -out s1b-s1a-s4-interferogram.tiff
+```
+
+From Python:
+
+```
+import otbApplication
+
+app = otbApplication.Registry.CreateApplication("SARInterferogram")
+
+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("indem", "S21E055.hgt")
+app.SetParameterInt("mlran", 3)
+app.SetParameterInt("mlazi", 3)
+app.SetParameterFloat("gain", 0.1)
+app.SetParameterString("out", "s1b-s1a-s4-interferogram.tiff")
+
+app.ExecuteAndWriteOutput()
