Calibrated SAR data

After the ingestion in the mCube of SAR EO data harvested from multiple sources, an initial processing is performed to calibrate the radar EO data product harvested from a notified source. SAR Calibrated EO-data are then offered ready for further generic processing as a Dataset.

The result comprises:

  • a series of single band assets for each polarization included in the EO data product, provided as full resolution calibrated data (Sigma Nought in dB),

  • a series of overview assets that provide three band combinations readily available in full resolution.

These assets represent process ready data for visualization and/or for on-demand processing.

In mCube the calibration of multi-mission SAR input products is done in a systematic fashion and is accomplished during the acquisitions ingestion phase.

SAR calibrated Datasets are pre-processed EO data with physically meaningful quantities (sigma nought) which enables a faster thematic processing by applying common operations according to the sensor type. A SAR calibrated Dataset includes both Sigma Nought single-band assets and visual products derived from them offered as multi-band overview assets.

A description of the Radar Products Calibration systematic service is available here.
