SAR Satellite On-Board Ship, Wind, and Sea State Detection

This paper describes a prototype implementation of ship, wind, and sea state detection algorithms for satellite on-board SAR processing designed for Maritime Situation Awareness. Existing algorithms were adapted to run on a Multi- Processor-System-On-Chip (MPSoC) combining an FPGA and an ARM CPU and further optimized for fast runtime on the system. The achieved processing times were 20 s for ship detection and 16 s for sea state detection on a 29Mpx SAR image. SAR processing is one component of a larger prototype system being developed in the frame of the H2020 project EO-ALERT, which further comprises an optical data chain, data compression/encryption, and delivery on multiple MPSoC boards.
