Progress report on the NASA/JPL airborne synthetic aperture radar system

AIRSAR has served as a test-bed for both imaging radar techniques and radar technologies for over a decade. In fact, the polarimetric, cross-track interferometric, and along-track interferometric radar techniques were all developed using AIRSAR. In this paper, we present the up-to-date system configuration and expected performance in the standard radar modes. In addition, we describe the various experimental modes available to researchers. Finally, we discuss on-going improvements with AIRSAR and future direction of the program.
