My take is Sensor system X has a detection range of Y. Inside of that range, you have a “blip”. Signal processing systems can refine the “blip” a little bit - higher TL or more advanced systems will get you more data. The skill comes in when you are 1) refining that “blip” down to a “400 ton Corsair” or 2) when you are operating outside of max range. So, Beaumont catches a blip, and determines that it’s a medium vessel, with minimal EM signature. They then pass the detection off to the Sr. Watch Officer, Serafina. Serafina trains the PEMS array on the target, and they are able to determine that it’s a 5,000 dTon vessel, running dark. Matching against known signal intelligence, they feel that it’s a Varger light cruiser. Ops decides to dispatch a drone to investigate. When the drone goes active near the target, it powers up its AEMS array. After a contested EO skill check with Beaumont, the target able to blind the drone by overwhelming it. However, Serafina is still on the PEMS array. They feel that there is no way that a Varger light cruiser would have EMS jammers capable of that, so they refine the detection, send it back thru signal, and suspect that it’s a Sword Worlder 10,000 dTon cruiser. Time for the destroyer to bug out.
