I am serious, can you tell me how you are doing it. I install, test and commission navigation radars, AIS, echo sounders and speed log on FPSOs, that's apart from the process control systems. I have a E&E degree from a reputable university with 15 years work experience spanning 3 continents. Please explain to my ignorant self how a marine radar can identify ships without AIS? How does it know that blob is ABc123 from Cosco. Tell me, enlighten me, surprise me with your wisdom... Lolol
Seriously it is not that hard identifying and tracking a large oil tanker. It is not an issue for the US Navy even to track hundreds of these tankers. Now tracking fishing boats may be another story.
