Wind fields are modified drastically in the coastal zone and have a large impact on human activities such as sea traffic and leisure, so that understanding of coastal wind fields is required. Synthetic Aperture Radar (SAR) is a unique tool, which can detect a wind speed map in near-coastal areas. Recently our group has established the L-band model function by comparing huge SAR-measured NRCS derived from JERS- 1/SAR with buoy and scatterometer-estimated winds. It, however, does not take account of incidence angle dependency due to constrain of the JERS-1 operation. Authors plan to develop the L-band model function with the incidence angle dependency by acquiring ALOS/PALSAR data by design. The improved model function will be useful for radiometric calibration of future L-band SAR as well as PALSAR.
