-https://sentinel.esa.int/web/sentinel/user-guides/sentinel-1-sar/acquisition-modes+==== COSMO+SAOCOM ==== 
 +<blockquote> 
 +The main difference between the two sensors is the wavelength: 3 cm for COSMO-SkyMed X-band and 23 cm for SAOCOM L-Band. This translates in the fact that while X-band can detect even slight details, L-band is suitable to observe larger objects which would result unclear with X-band. Combining the two is possible to monitor both geometrical objects and small details.
