LORO is the normal guidance mode. It is quite adequate with appropriate fuse action for low level fire. You need the gated proximity mode, and to inhibit lead on diving low altitude targets - the left hand switch in the Volkhoz 'z' Screen.
For rapid acquisition of a valid elevation/azimuth range if two targets are at the same range, the easiest method is to take cueing from the IADS hand-off. Then you just lock up the target which is centred under the az/el/range lines. Still the combination of closure rate and acquisition time/missile flight time prevent more than two targets in formation being taken under fire by a single battery.
If you don't want to use IADS, then offset the azimuth until only one target is showing strongly, the elevation that remains matches the target on the near side, and the other az/el pair the target on the far side of the formation bearing. This is fairly subtle though and it isn't foolproof.
With the low altitude switch however, the only radar mode is Wide Beam.
