I am acknowledged that some AGM-65 are radar guided.
In historical, any variants of AGM-65 family has not been radar guided about each missile's seeker head.
Seeker Homing types:
1. Electro-optical TV camera (only visible light; daytime only)
A,B
2. CCD TV camera (almost only visible light; daytime and morning / early evening)
H,J,K
3. Imaging infrared (in the other words, TV camera using IR; day and night workable, but impossible in too heat summer or desert)
D,F,G
4. Semi Active Laser (a Laser Designator is needed on the carrier aircraft or the buddy aircraft, ground JTAC)
E
So, all variants use some types or
Ray (Visible ray, Infrared ray, Laser) and cannot lock-on the ground targets behind clouds.
But ground radar is not needed on carrier jets to operate AGM-65 variants.
(EDIT)
And FLIR is necessary only about E subtype. Others not.
Searching ground enemies will become easier with FLIR for D,F,G variants, though.
Besides Seeker types of missiles' their own; cooperation between AGM-65's seeker cameras and carrier's ground radar might be implemented on some modern jets and Fire Control Systems.
I'm not sure correct information what jets' what subtypes have such integrated systems (perhaps night attack variants of F/A-18D/F + some modernized C/E , night attack and CCIP variants of F-16 , F-15E), but they might have those functions like....
- Searching ground targets by its radar in ground search mode and after found .... lock-on it.
- FCS tells its radar locked Azimuth and Angle to AGM-65's seeker. AGM-65's seeker follows given data.
- Now AGM-65's seeker TV camera may capture the same ground object carrier's radar locked.
- Easy to lock-on operation about AGM-65's own seeker.
Such integrated implementation is not done on any mods in IL-2 1946.
But some spare interfaces are added in Engine mod 2.8.x for future expansion.
