<p class="Abstract">During the recent years, maritime surveillance has been
receiving a growing interest. Ship detection and identification are parts of
maritime surveillance in order to dealing with illegal fishery, maritime
traffic, sea border activity, or oil spill detection and monitoring. Nowadays,
Synthetic Aperture Radar (SAR) as one of active remote sensing technology
provide signals to penetrate cloud, can be advantage to be used in tropical
region with the intention to monitor sea objects on the sea surface from the
space. The availability of Sentinel-1 as SAR imaging mission, providing
continuous all-weather, day-and-night imagery, makes it ideal for precise
cueing and location of ship activities at sea. Utilization of CFAR (Constant
False Alarm Rate) algorithm provided by SNAP (Sentinel Application Platform)
software from ESA show rapid detection of ship in the study areas (Madura
Strait and Lamong Gulf). Compared with manual ship extraction method, it gives
sufficient results.<o:p></o:p></p>
