+
+## Description
+
+This file is an interferometry chain between multitemporal SAR images. 
+One master image is fixed by users and other images are processed as slave image.
+
+For each couple (master/slave), the processing is divided into four parts descrided below :
+
+* Pre-Processing Chain
+
+
+* Ground Chain
+
+
+* DIn-SAR Chain
+
+
+* Post-Processing Chain : Orthorectification for final interferogram, multilook processing ...
+
+## Launch this chain
+
+This Python script takes a configuration file (.json) as input and several arguments such as a date of beginning/ending, master image or others options for orthorectorectification ...
+
+The configuration file has always the same organization :
+
+![image](../Art/conf_chains/MultiSlc_Chain.png)
+
+Four sections compose the configuration file :
+
+
+* Global :
+
+
+    * **SRTMShapefile :** .
+
+
+    * **Datalake :** 
+
+
+    * **Geoid :** 
+
+
+
+* Pre_Processing :
+
+
+    * **doppler_file :** Output file to store Doppler0 result
+
+
+    * **ML_gain :** Gain applied on MultiLooked images
+
+
+* Metadata_Correction :
+
+
+    * **fine_metadata_file :** Output file to corrected metadata
+
+
+    * **activate :** Boolean to activate this chain (By default false)
+
+
+    * **GridStep_range :** Step for the correlation grid on range dimension
+
+
+    * **GridStep_azimut :** Step for the correlation grid on azimut dimension
+
+
+* DIn_SAR :
+
+
+    * **GridStep_range :** Step for the deformation grid on range dimension
+
+
+    * **GridStep_azimut :** Step for the deformation grid on azimut dimensio
+
+
+    * **GridStep_Threshold :** Threshold for the correlation grid (applied on correlation rate)
+
+
+    * **Grid_Gap :** Maximum gap between DEM grid values and the mean value. If the difference betwwen a value of the DEM grid ans the mena is superior to this gap then the value is set to the mean. (Avoid incoherent shift)
+
+
+    * **Interferogram_gain  :** Gain applied on amplitude band of output inteferegram.
