БРЭО самолетов Ло

From what I understand, the transition "from ДВБ to БВБ mode" during the lock-on does not affect gyro-stabilization.

мое мнение - при РНП антенна уже зафиксирована (non-gyrostabilization). Возможно с этим связано продолжительное время - до 7 сек - при постановке цели на автосопровождение из ДБВ (время для выравнивания антенны при смене параметров облучения без срыва захвата, а не только уточнение параметров цели).

"In this mode, the coverages are similar to those in the ENCOUNTER (В) and PURSUIT (Д) modes. That is - when the target flies on the head-on course, the target detection occurs at the ranges similar to those in the ENCOUNTER mode. From the range less than 30 km, the target blip is observed in each scanning cycle (Hi PRF and Med PRF) due to the measurements also at the medium repetition frequency (at the ranges less than 10 km, ONLY at the medium repetition frequency)."

So - at the ranges less than 10 km, only the Med PRF can detect the target? It means - lock on must use Med PRF at ranges less than 10 km, and this is the reason to "change over to БВБ mode at 10 km range".

Да, думаю так. Но "only the Med PRF" не совсем верно, на такой дальности предпочтительней использовать Med PRF(почему - писал ранее) .

It may also answer the question - in what regime will be the radar, if the lock-on is broken? If the lock-on was broken at the range less than 10 km, it is advantageous for the radar to return to БВБ mode, instead of ДВБ mode, so to more quickly re-acquire the near target. If it's desired to resume ДВБ search mode, the pilot should press the "reset" switch.

задал такой же вопрос пилоту Мига - жду ответа . Меня смущает что кроме режима "вертикального скантрования" ("БлБой") у радара больше нет вариантов.

To say that the antenna will suddenly change the coordinate system - that is, to rotate mechanically from gyro-stabilized to non-gyro-stabilized position at 10 km distance - it's almost impossible to believe. The angular velocity of the target is faster at short range, so it's a sure way to completely lose the lock. Much more probable is that during the 2-7 seconds required to accomplish the initial ДВБ lock on, that is the time when the antenna is changing from gyro-stabilized to non-gyro-stabilized, IMHO.

... пришли к одному выводу - см. выше

My suspicion: aircraft roll does not break the lock, neither for Russian nor for western fighters.

Я тоже так думаю, но жду ответов пилота Мига или документальных подтверждений.
