This product is a complex, slant-range, digital image generated from Level 0 data collected when the instrument is in Alternating Polarisation mode. (7 possible swaths). It contains two CO-registered images corresponding to one of the three polarisation combination submodes (HH and VV, HH and HV, VV and VH).
In addition, the product uses the Range Doppler algorithm and the most up to date processing parameters available at the time of processing. It can be used to derive higher level products for SAR image quality assessment, calibration, and interferometric applications, if allowed by the instrument acquisition.
A minimum number of corrections and interpolations are performed on the data in order to allow the end-user maximum freedom to derive higher level products. Complex output data is retained to avoid loss of information. Absolute calibration parameters are available depending on external calibration activities and are provided in the product annotations.
Spatial Resolution: approximately 8m slant range x approximately 4m azimuth
| Spatial coverage: |
90 N, 90 S, 180 W, 180 E |
| Temporal coverage: | 2002-11-15 - 2012-04-08 |
Data is available online after registration for the (A)SAR On The Fly Service.
