blue arrow DESCRIPTION

This ASAR Alternating Polarization Level 0 (Co-polar) 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_APC_0P corresponds to the polarisation combination HH/VV= H and H received/V transmit and V received. Auxiliary data include Orbit data and time correlation parameters, PCD (Noise Measurements, Calibration Pulses P1, P1a, P2, P3, Header content of Source Packet).

Data Size: 56-100 km across track x 100 km along track
