There's a limit to the number of targeting systems you can afford to deploy on a weapon, and there's the problem of reconciling their signals if their views of where the target is start to diverge.

"Counter-blinkenlights" are well-known as thermal flares, and more similar but as crude, [dazzlers] that blind the incoming rockets' sensors.

AFAIU, a dazzler is intended to blind the whole sensor, so home on dazzler would need specialized hardware, not only a software adjustment. (Replying to other messages in this thread)

But it's not a separate system, it's just a separate algorithm - it's software.

"No target" by AI but "target" by the "engage light sources" recognizer is still successful targeting.

"No target" versus "aim at anything not green or blue" is as well.

It's also a question of the speeds involved: a dazzler on high speed jet versus a high speed missile might cause a near miss which means hundreds of meters of actual separation. Diving drone vs. truck? Not so much.
