Sentinel-1 near real-time application for maritime situational awareness

In the context of the project real-time services for maritime security (Echtzeitdienste fur die Maritime Sicherheitsecurity), an experimental research platform for validation of maritime products derived from remote sensing data, was developed. This article describes the work carried out to derive ship-, wind-, and wave detection products out of Sentinel-1 remote-sensing data by DLR's Maritime Safety and Security Lab in Neustrelitz, part of the German Remote Data Center DFD. The activity aims to the fulfilment of project requirements, primarily to support the need for near real-time performance up to 15min, as those in maritime situational awareness. The development and implementation cover the task of level 0 processing, based on DLR's front end processor, the implementation of the framework for real-time processing up to level 2 (value adding), as well as the development of a hardware-independent virtual-processing platform.
