I thought the radio/data-link used for LOAL could have a tactical use in emission controlled IADS operation. But your SAM sim indicate that it has no tactical use.

I had a few minutes to further research on the S-200-Talash topic. While the CW radars 5N62 and HIPIR of the HAWK use two separate antenna for transmit and receive CW signals, the 1S91 of the SA-6 uses a single antenna. So my impression was false.

The system in the third photo is directly connected to the Sayyad-2 SAM but the larger antenna system in the second photo is unknown and could be a 1S91 like design for FMCW illumination of the S-200. But for that task the antenna seems to be too small, hence this system could be a early Sayyad-2 illumination radar replaced by the more advanced one in the third photo.
