Study of Scattering Properties of Oil platforms in Caspian Sea as Stable Radar Scatterers according to PALSAR Data

An analysis of oil platforms long-term stability in Caspian Sea seen on the Japanese synthetic aperture radar PALSAR images is made. It is shown that typical radar cross section stability of oil platforms is about 0.5 dB, what is close to the parameters of specially designed calibration targets. Possibility of SARs intercalibration using the oil platforms under study is demonstrated.
