In case of failure of target tracking after the R-27Pl missile’s descent at short ranges, the pilot should vigorously turn to the target to provide illumination in the view mode due to radiation on the side lobes of the antenna pattern and perform recapture of the target.
That appears to be talking about when the missile has closed to short range and is being guided by the reflected radar energy rather than by datalink. This part is quite explicit in saying that datalink is not resumed:
5.6.5. If the RLPK target acquisition fails, after the missile leaves CSG and re-capture of the same target, the DNP mode for the launched missile is not resumed.
I guess going to be like every missile having an inverse monopulse seeker in-game, every missile/radar set can reactivate and relock regardless of technical limitations irl
Discrete-Continuous Illumination (DNP) mode, when an attacked target is tracked and cueing is performed and transmitted to the missile via the RC line (radio correction for missiles with FTC);
