This findings is historical and have nothing to do on what type of ships different sensors will occour ingame. But it gives you a clue on what kind of sensor you dealing whit when you try to mod.
Oddly i found that the sensors ingame is way of the accuracy what they actually performed in reality. The range for an example of most of the radar ingame is not accurate what they actually had in real.
