ASAR Image Mode source packets Level 0Entry ID: ASA_IM_0P
Abstract: The Image Mode Level 0 product consists of time-ordered Annotated Instrument
Source Packets (AISPs) collected while the instrument is in Image Mode. The
echo samples contained in the AISPs are compressed to 4 bits/sample using
Flexible Block Adaptive Quantisation (FBAQ). This is a high-rate, narrow swath
mode so data is only acquired for partial orbit segments and may be from one of
seven possible ... image swaths.
Details of extracting level 0 data are explained below and in the section.
The Level 0 product is produced systematically for all data acquired within
this mode. The NRT version of the product is available from the PDHS 1 day
after data acquisition, while the OFL (fully consolidated) version is available
from the PAC after 2 weeks.
