Use of machine learning to develop algorithms for distinguishing iceberg and vessel targets require abound of validated data sets that are often costly, time consuming and, in some cases, inaccessible. Generating electromagnetic (EM) backscatter models of iceberg and ship targets can be a vital step to develop robust iceberg/ship classifier. Here, development of an EM backscatter model of various icebergs has been presented and compared with ground truth data. GRECOSAR, a satellite EM backscatter modelling tool is used with the imaging scene consisting of iceberg targets surrounded by the ocean surface. The 3D CAD models of the icebergs were obtained in a field program off the coast of Salvage, Newfoundland and Labrador, Canada. While profiling the iceberg targets, a SAR image from Sentinel 1A was captured and compared with the simulated SAR images. Comparisons made in terms of total radar cross section (TRCS) and the morphology of the targets generally indicate a good agreement.
