About this service

The SAR instrument onboard the Sentinel-1 satellites is an all-day/all-weather remote sensing instrument.
As it is an active radar instrument it does not require daylight for imaging, and the radar signal penetrates clouds and precipitation.
Processing the received radar signals into imagery is a complex and resource demanding process, commonly referred to as SAR focusing.
In the traditional processing systems the focusing is done on complete raw data products after reception.
The Sentinel-1 NRT-SAR system on the other hand is able to focus the SAR data in a pipeline process, where processing is run in parallel with raw data reception. Sentinel-1 NRT-SAR delivers individual focused “bursts” of data to downstream services, making it possible to provide end services for the customers in quasi real time.
NRT-SAR can deliver bursts in Single Look Complex (SLC) format suitable for advanced further analysis, or as Ground Range Detected (GRD) bursts in raw formats suitable for more standard image processing services.
