The AIRSAR radar antennas are mounted on the lower aft
port side of the DC-8 aircraft. These antennas are used to collect data
in all modes. There are polarimetric SAR (POLSAR), Cross-track interferometric
SAR (TOPSAR) and along-track interferometric SAR (ATI) modes. The L-band
ATI uses an additional antenna ( not shown) located on the lower port side,
forward of the wing . The physical dimensions of AIRSAR antennas are shown
as follows:
