@Eagle-Eye:
I don’t think HOJ on its own is used to make a hit. It’s meant to get a missile close enough for a burn-through by its own RADAR.
Similar to how the latest AGM-88 uses its passive sensor to guide in on the area where radio signals are sent out by the target’s RADAR, and then switch to active millimetre wave scanning to pinpoint the target during the terminal phase of flight.
HOJ does not need a burn through, that’s the whole point of HOJ… An autonomous HOJ-capable missile is basically just looking to hit whoever’s making the loudest noise, and the jammer is the one screaming. Once the jammer is deactivated, its carrier is as loud (or quiet, rather) as everyone else around him, and the only way to pick him out again is by active scanning.
That’s exactly why it’s a major disadvantage to keep your jammer on beyond burn-through range. It provides no benefit to you anymore, while it does put a major “HIT ME”-sign on your back.
As you can see in both your ACMI’s, when the lock is broken, the missile is still very far from target (25 and 19NM respectively) and looking at an empty sky, as it has climbed significantly (14,000 and 10,000ft) to maximise range (because you launched at 30NM, which is way too far to get a proper Pk on a manoeuvring target anyway).
-
In the first flight, when the lock is broken, the missile just continues its ballistic path, as that is probably where it would expect the target (based on latest datalink information fed by your aircraft). Because the target cranks towards you again while nobody is looking, however, the lead course is no longer correct, and the missile is unable to pick up anything.
-
In the second flight, the lock is lost and the missile makes an adjustment towards the target, presumably based on latest datalink info again. At 7 - 10NM, it’s looking directly at the target, but probably still too far out to really find anything with its own RADAR, and by the time it gets close enough (<5NM), the target has already left the missile’s gimbals, or the missile is no longer able to correct course without losing all its momentum. (speculation -> ) This may have been different had the target continued to point its ECM towards the missile, as it may have had something to guide towards at earlier stages of flight.
Unfortunately, I’m unable to test this myself at this time, as I don’t have a human opponent available.
What aircraft were you targeting from within the SU-27? An F-16? If so, the RCS of a SU-27 is 15m², while that of an F-16C is only 1.2m² (according to Global Security, obviously also depends on geometry). Should be no surprise you can spot and track something bigger more easily.
Also keep in mind that the RADAR of an F-16 is different to the one of a SU-27, so its scanning capabilities, detection range, filter etc. will be different. To make a more proper comparison, you should pit two aircraft with identical RADAR sets but different RCS (e.g. MiG-29 and SU-27) against each other, and see when you achieve burn-through.
THX for the reply, but I’ve made some test which confirm the MADDOG won’t get U in the HOJ.

>>>>>ACMI<<<<<<<
AS U can see from the ACMI:
1st round, when Maddog fired directly at a Jammer from medium range(carefully aimed and spread launch to cover more area), missile go ballistic path and fall because they can’t find any target with their own seeker. NO HOJ sighted.
2nd round, when launch at close range(inside 22NM already burn through), Only 1 missile luckly to get a track at end game, but obviously base on it’s own boresight seeker because the missile keep a straight line until 8.5NM which is the MPRF range, the active seeker happened to see the target and followed up. NO HOJ sighted either.
All 8 missiles in the demo does NOT turn a single bit before any MPRF capture. No AIM-120 follows the Jamming aircraft autonomously, they just fly straight ahead try to obtain some bad luckly guy with the boresight seeker.
So based on these observations, we can conclude that MADDOG will NOT activate HOJ, and won’t track any Jamming target “autonomously”.

Last, if U test with a human pilot compared with AI (both F-16BLOCK52 vs Su27), U can see the great difference between burn through range: 35NM+(AI su27) VS 20.5NM(human su27).
But thx anyway~
