Monitoring of marine laver cultivation using two ALOS-PALSAR PLR acquisition mode data

This study attempts to describe the scattering analysis of the marine lavers which are placed around the coast of Yellow sea in South Korea. The data acquired by Phase Array L-band SAR (PALSAR) on board of Advanced Land Observing Satellite (ALOS) at different dates and years of an acquisition but of the same month. The laver area, consisting of buoy, bamboo and net. They show the different signal signature patterns due to variation in the metrological conditions on an image. The analysis, monitoring and detection were performed by means of the 4-component scattering analysis along with entropy (H)/alpha (a) angle plane distribution over an image. Radar cross section (RCS) of laver area shows less value as compared to the background value under the moderate wind speed condition. Morphological operation was then carried out with the use of obtained relative threshold values based on the distribution plane.
