Radar on an oceanic buoy is probably more efficient. Ocean buoys are giant metal spheres with some concrete ballast to add stability, attached via steel cable to an old train freight car used as an anchor. You can throw a couple hundred watts of solar and electronics on there no problem. There's hundreds of these things scattered about in the ocean for oceanic research/weather forecasting, not a new technology. Modern, consumer-grade solid state radar ($1200, off the shelf at Amazon or West Marine, google "4G radar") can pick up seagulls sitting on the water at 500 feet, or track a tiny ski 4 person boat at 10 miles.
Before you ask, no, there is no such thing as a stealth radar fishing boat.

- nradov 5y agoWe're talking about a vast area of ocean. Each buoy would only be able to monitor a small circle. There are limits to anchoring depth so they can usually only be used close to score. And marine electronics require frequent maintenance due to the harsh environment.
- hadlock 5y agoOn page 42 they talk about two different mooring systems for buoys up to 6000m in depth. Average ocean depth is approx 3000m. Marine electronics are considerably more robust than you give them credit. All my consumer grade electronics on my boat were installed in 2001 and with the exception of one LCD display are all in perfect working order. https://library.wmo.int/doc_num.php?explnum_id=7053 https://library.wmo.int/doc_num.php?explnum_id=7053
