Unlike the seeker of the Maverick missiles, (Those) equipped with a TV-correlation seeker.
~~ This means that such seeker will not be able to lock on single ground targets
~~
if the enemy’s tank changes its position, then the drop will be done on an empty spot.
vs
(Contrast) Seekers like these can track optically contrast objects
~~ we allow seekers to lock on any point on the ground.
~~
So any point on the ground is considered contrast object.
Yeah point on the ground, not object on said ground. Literally stated the thing just worded differently. Not getting where you think they’re saying different things.
They are talking about tracking functions that fundamentally work in opposite ways (contrast vs correlation), the fact that they do the same thing, is the issue as they are conflating two wildly different techniques.
Contrast techniques work by correcting for pointing error of the stabilized Seeker, comparing the computed location of the centroid of the target being tracked, as it moves across the FOV and attempt to maneuver the airframe to zero out the apparent movement of the target centroid, thus establish & maintain the intercept’s required geometry thought the flight, the same way most missiles do.
Correlation works by tracking spatial relationships between the entire image (or multiple smaller sections of the image) vs what it was at launch and so can be targeted at * low / zero contrast targets*(e.g. the ground, which obviously would not be able to be tracked by the former due to insufficient available contrast), or even specific locations regardless of contrast since its the relationship between them that matters.
Of course the latter is much more likely to break lock, and will stop correcting for errors in its flight path earlier for regular targets one the field of view changes sufficiently.
There is a funny story here.
Some russian players in forum cried everywhere about their kab bomb.They showed up in many forums like SPF and reddit posting thing like “Is there any evidence walleye can’t track moving target”.“Is there any evidence kab-500kr can track moving target”
And some clowns even posted a issue,they posted some description about bomb and said
“In short, the Russian equivalent of the American “smart bomb” was better. So it should track moving targets.”
Of course the issue was “not a bug”,
but gaijin still secretly gave Kab-500kr ability to track moving tanks in a update for unknown reason.
I think the reason was that seeker was apparently modernized / revised at some point under the same designation that resampled the comparison image for later computational cycles every so often.
Theoretically allowing for significant changes in the scene to be accounted for. but from what I remember of the discussion the proof provided was weak, and inconclusive about when it was even designed, let alone accepted in to service.
The main user of basic kab-500kr in game is MIG27M/K,since russian mig27s retired in 1993.I really doubt they can get the new bombs(if exist).
Actually the correlation seeker problem still exist.
The new Kh-38MT in dev.Gajin is using data much older than the missile,which made it a 40km 2.2M missile.But the manufacturer of missile changed its description in 2022,and claimed its a 70km range missile flying at 350-380m/s.
And we know almost nothing about seeker,and i really want to know how gaijin know its a contrast IR seeker.
So looks like the bucc s.2B radar is picking stuff up and working now. Not sure how its supposed to work but might help out in getting aim9Ls on target I guess? Though I thought it was supposed to be a ground radar, maybe thinking wrong plane.
