Pulse repetition frequency and lock stability

[asparagin]

This is something I wondered since 1.12. In the Su-27 (Su 33 also) you have the possibility to chance the pulse repetition frequency (eng: HI and MED) which helps detecting a target sooner if you know that it is coming towards you respectively away from you.

Choosing ILV, you have a little of both worlds but reduces the range with 25%.

So it's clear that it is all about the range. But theoretically this should also have an impact on the lock stability.

Eg.: target flies towards me, I am in HI and lock him, he should have a harder time to notch than if I were in ILV (This behavior is for sure range dependent).

So, is this modeled or not?

 

PS: notching is not the best example because his course changes to perpendicular, but other means to weaken lock.

yes, you can change PRF in every fighter. HI is for targets traveling at you, MED is for targets trying to get AWAY from you, and ILV is a compromise of the 2 but with reduced range (holds better at targets trying to notch).

 

HI is better for BVR tactics planning but once the range decreases ILV is better for holding lock to get the weapons on the mark.

so it does influence the strength of the lock..

yes, plus if target manages to pull a good notch (for not too long) it will reacquire better at the end of the notch whereas in HI or med it wont. This also true for F-15 even though IRL PRF is managed automatically.

Agreed! Especially at closer ranges when you need to scan quickly through all hemispheres, the AUTO (ILV) mode is best! The range reduction will not come into play at this point because the bandit will be close enough already anyhow...

 

About the lock strength im not too sure, AFAIK in Russian AC, the radar switches to "Attack" mode once you lock up a target, so it doesn't really matter which mode u locked him with prior...

 

Im not too sure about F15 though, now that it also has the ability to switch PRF modes in FC2

Exactly. It makes sense like this.

That is the question. Does the attack mode also depend on how the radar energy is distributed, or it will focus on one target with all energy.

Same thing for F-15 since its clone of the Su-27 radar with TWS multi track ability...well kinda off. :D
