Black Aces Message Board

Best I have seen, so sharing it here so we can go back and review.

(Best to click the YouTube link on the bottom so you can see it full screen. I think the message board interface crops it a bit.)

4 minutes into this tutorial and I'm already hearing wrong information, not a great start....

Medium pulse repetition frequency(MPRF) is not used for "close in contacts", its best used to find targets that are cold from you, flying away from you.

edit: "if the bandit is outside 25 nm, use high PRF"
yeah no, high PRF is for contacts that are hot with your aircraft, pointed toward you. Range has nothing to do with it.

He kinda demonstrates the validity of his assertions regarding PRF, which is possibly different in the sim than in real life.

Oddly enough, without having any previous direction on which should be used when and just trying to figure it out, I guessed that high PRF should be used close in and medium should be used at higher ranges. My thinking was that PRF basically determines the space between the pulses. If a high PRF is used, the spaces will be shorter and at longer ranges a pulse might start before the previous one makes it back to the antenna which would likely confuse the radar. I wouldn't think closing speed would have too much to do with it. But, like I said, that is what I came up just trying to think through it logically without any real education on the subject.
