Abstract :
The goal of the paper is to demonstrate radiometric stability of PALSAR instrument on 4 years time interval using new type of calibration targets strong passive scatterers of both artificial and natural origin. Artificial targets used in our study were parabolic antennas located at Special Design Bureau of Moscow Power Engineering Institute (SDB MPEI) calibration site. Natural calibration targets we selected for calibration were bright scattering objects identified in urban and industrial areas near SDB MPEI calibration site in Moscow region, Russia.
