The estimation of sea ice density using the ALOS/PALSAR data - To make sea ice condition chart for safety navigation of Okhotsk sea

摘要

ALOS PALSAR is an active type microwave sensor which can observe regardless of weather conditions. We developed the method for estimation of sea ice density using the PALSAR data automatically. Moreover we constructed the system to provide the analyzed PALSAR data in near real time. Further we verified that it contribute to reducing the days, in the case to transmit the chart with no information by the series of operations in our project.
