Locating a force without identifying every ship

Would radar emissions only indicate a broad area for scouting, or could they locate a task force accurately?

Sustained emissions can give an accurate position, although they may not reveal which ship is transmitting.

A follow-up asks whether radar emissions would merely identify a general area to search. An emitter transmitting long enough in active search can permit a much more accurate position estimate. The remaining limitation is identifying exactly which ship produced the signal. It can therefore help locate a task force without fully identifying its composition.
