It depends on the missile you are using.
With semi-active missile, you need an illuminator radar that is locked on to the target in which the missile homes into the reflected illuminator signal.
With active missile the telemetry from the long range radar will be punched into the missile. The missile will head towards the location that was punched in and turn on it's own homing distance and lock on with own radar.
With more advance active homing missile you can re-send telemetry during mid flight but basically it is all the same.
Land attack missile like cruise missile can use GPS and even image sensor terminal control.
