It is bearing rate actually that is calculated by the stopwatch in order to give the speed of the target. Of course, the bearing rate changes so you have to keep no more than 3minutes for calculation. Furthermore, the greater the bearing change (great AoB, high speed) the more accurate the bearing rate is.

Ahh,he wanted to know how bearing is calculated,I thought he wanted to actually know what bearing WAS
