Chapter Analysis of the limits for the detection of small garbage island immersed in clutter radar
Summary
This study analyzed the detection limits of X-band radars for identifying small floating aggregations of plastic marine litter (Small Garbage Islands) under varying sea conditions. Measurement campaigns confirmed that X-band radars can detect surface plastic aggregations, though sea state significantly affects detection capacity.
This work show the limits of the detection capacity of X-band radars, as the sea state changes, in order to identify, discriminate, characterize and track small floating aggregations of plastic marine litter (Small Garbage Island - SGIs). Two distinct radar measurement campaigns were conducted at sea of SGI modules assembled in the laboratory. The measurement were carried out respectively in conditions of calm sea, to test the system in ideal conditions, and in rough sea conditions. The data analysis confirmed the ability of the X-band radars to detect the aggregations of floating waste on the sea surface.
