                         coast region of northern Brazil. Data were acquired with a SAR 
                         R99B sensor from the Amazon Surveillance System (SIVAM) on board a 
                         Brazilian Air Force jet. Flights took place in the framework of 
                         the 2005 MAPSAR simulation campaign, a German-Brazilian 
                         feasibility study focusing on a L-band SAR satellite. Information 
                         retrieval was based on the recognition of the interaction between 
                         a radar signal and shallow-water morphology in intertidal areas, 
                         coastal dunes, mangroves, marshes and the coastal plateau. 
                         Regarding the performance of polarizations, VV was superior for 
                         recognizing intertidal area morphology under low spring tide 
                         conditions; HH for mapping coastal environments covered with 
                         forest and scrub vegetation such as mangrove and vegetated dunes, 
                         and HV was suitable for distinguishing transition zones between 
                         mangroves and coastal plateau. The statistical results for the 
                         classification maps expressed by kappa index and general accuracy 
                         were 83.3% and 0.734 for the multi-polarized color composition 
                         (R-HH, G-HV, B-VV), 80.7% and 0.694% for HH, 79.7% and 0.673% for 
                         VV, and 77.9% and 0.645% for HV amplitude image. The results 
                         indicate that use of multi-polarized L-band SAR is a valuable 
                         source of information aiming at the identification and 
                         discrimination of distinct geomorphic targets in tropical
