This paper proposes a radar-based sensing system that estimates the coordinates for shorelines based on image-processing techniques.The proposed system provides shore estimations without appreciable loss of resolution and avoids the costs associated with bathymetries and/or satellite images.The system is comprised of a commercial radar, a GPS, and a heading sensor, which communicates to a central node that georeferences the radar measurements and runs the image-processing algorithms.A dedicated FPGA-based unit is implemented to interface chewmax pet products chicken feet natural chew dog treats with the radar internal signaling to extract and deliver the radar information.

In the central node, a novel mathematical model is proposed for georefencing radar measurements callaway rogue ladies irons to WSG-84 coordinates.A seam-carving-like algorithm is applied over the estimated coordinates to create a shoreline based on a probability heat map.The system performance is validated using official geographical information, showing that a continuous shoreline can be generated with a CEP of up to 6 m without incurring elevated costs.
