| SAR mode identifier |
| SAR_mode_id_l1b_echo_plrm |
SAR mode identifier is a flag that indicates the tracking mode of the SRAL instrument:
- closed-loop mode: autonomous positioning of the range window using the median algorithm.
- open-loop mode: range window position based on a priori knowledge of terrain altitude derived from a Digital Elevation Model (DEM).
- open-loop mode fixed gain: range window position based on a priori knowledge of terrain altitude derived from a Digital Elevation Model (DEM) set to a fixed gain.
