This ASAR Alternating Polarization Level 0 (Cross polar V) product contains time-ordered AISPs corresponding to one of the three possible polarisation combinations: HH & HV, VV & VH and HH & VV, respectively). The echo samples in the AISPs have been compressed to 4 bits/sample using 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 different image swaths.
ASA_APV_0P corresponds to the polarisation combination VV/VH.The Level 0 product is produced systematically for all data acquired within this mode.
Data Size: 56-100 km across track x 100 km along track
