Weapon vs normal aircraft track I've read that some radars can detect stealth aircraft or aircraft with low radar cross section but are not powerful enough to allow a &quot;weapons&quot; track or allow a missile or another aircraft to lock on to it.
What is the difference between the 2 radar tracks? Is one less accurate in terms of pinpointing the aircraft range by a few meters or kms?
Virtually any radar in the world can detect and track a stealth aircraft as well as to provide a “kill chain” to direct and guide weapons at it.  The key is at exactly what range they can do this and that’s a function of the radar cross section of the target.  Stealth aircraft typically, depending on the bearing and azimuth a radar illuminates them from have an RCS on the order of a BB pellet; a conventional aircraft eg a SU-27 has an RCS around the size of a two story house.  Certain kinds of radar sets like low frequency radars can detect stealth aircraft much better than X-band radars can but are inferior for miniaturization or for providing weapons guidance, limiting their effective ranges.
