Detection has nothing to do with tracking. This RADAR type is Early Warning (EW) and is meant to hand off to a Target Tracker (TT) by providing range, bearing and altitude.
That is true with all IADS, but with a resolution that can only get you within 10,000 meters you are asking a lot of most Target Track platforms that only have a 1 degree beam width. 10km is a lot of damn sky to search. Plus you will have to have multiple systems up radiating. Those systems have now told the enemy where they are.
