PS. Guys, I need a detailed description about how Dvina/Volkhov are calculating lead in K/UPR modes, what kind and how exactly they got information ( speed, distance...?)
Hi, there... It's about Volkhov/Dvina family. We all know, that if we can launch a missile without tracking the target. When the missile drop the first stage and start receiving commands from SNR, it must follow the boresights position at the moment (after some oscilations). I think it is like RS should be. As I see missile reacts just like that on epsilon and beta, ut still can't figure it out is moving the range boresight reflecting on missile, or not. Also, when practicing on Ashuluk in UPR/K: - against supersonic target the lead hits 4 degrees mark - against subsonic target - lead is not more than 3 degrees When the target denies data about speed and parameter (i.e. noise jamming), how could react the APP if there is no data for speed, parameter? P.S. Please, anybody, check on Hungary training with Volkhov, missiles are not guidable!!!Everything is fine, guys, I've just messed up the switches...

As I see missile reacts just like that on epsilon and beta, ut still can't figure it out is moving the range boresight reflecting on missile, or not.Basically you should see no effect, except for K method, where the added elevation is depending on target range. Also, when practicing on Ashuluk in UPR/K:
- against supersonic target the lead hits 4 degrees mark
- against subsonic target - lead is not more than 3 degreesCorrect. Subsonic target UPR point is closer to the target. It can be less than 4 degree, depending on the P. Supersonic target UPR point is further to the target. It can be more than 4 degree, but the system allows the missile max 4 degree. When the missile is flying at less than 4 degree, than it is directly goes towards the UPR point. When the missile is flying at 4 degree, than the UPR point is at probably more than 4 degree, just the system limits its lead angle.

Hi, Hpasp, Recently you explained about the K3 command in Volkhov - in case the missile missed the target, or button VOZVRAT is pushed, SNR transmits K3 command for second time. I missed some target on purpose, but never saw K3 light to lit again. (I wanted to check it with VOZVRAT, but still I am not fast enough to switch the screen so fast  ). And, sure somebody mention it - electronic shots are traceable on Target Acquisition Radars...

Hello Hpasp! Error in the Volkhov "Divide by 0" Look at the picture !

Is that true? Could you check it with your sources? I do not understand it, please translate.

You just super Piston79! You managed to shoot down the SR-71 Dvina ! I see a report on the Method K to small distances ! The question is how did you manage Dvina ?

No, I didn't shot it down, only scratch it... And you can see how from atached report. If you don't get it how, I'll write, but after 9 hours (because I'm going to work).

Piston, have you noticed the Habu's altitude in AAR? 10-12 km? Seems suicidal... or another bug. Not a bug, just this is the altitude Piston set. (He set the target distance manually) Just use SINE function to find out... http://en.wikipedia.org/wiki/SineTarget distance: 34km Target elevation: 18° Target altitude: 10,6km

Thanks, every day would bring new knowledge...  ...if only my primary school teachers hadn't been faster in this case. My point was that so far AAR referred to real target altitude, not a SNR setting. Have you changed it in the meantime?
