You are right about the Aob; I arbitrarely set Aob = theta in my derivation ( a little cheat, I suppose  ). |
Hello TorpX,
yes...i told you from first moment that it is a very little 'cheat' that allows to formula give 'acceptable' results for target's speed.
(i only posted for the ones that are 'funs' of 100% correct formulas...not becuase will see any big difference in-game.it was more ...'theoritical'...the whole subject)

thats a good question! for me , there is no method that can be named as 'bad'....every method has always advantages and disadvantages when comparing each other.
this specific method has one very good advantage : doesn't need to know the range to target ....it needs ONLY target's length and target's direction (for getting the angle lb)...BUT ,on the other hand, has a lot of disadvantages : u-boat's speed...hard to keep this constant and at sh you never know if your own speed is 3,7 or 3,8kts .other disadvantage is that you have to keep own course constant during the procedure ...also hard to achieve this in sh.
so, no i don't use it ...i prefer(if i am running after for a fast solution) to get some range measures and draw the true course of target(not only its direction) . then things are getting very simple: take one bearing to target and mark the point that intercept target's course and then after x time take a second bearing to target and mark again its position on its course line. thats enough then to get its speed
my prefered ultimate method is ''the 4 bearings method'' ...i think that nothing can 'beat' this method(no need to keep constant anything but time intervals,no need to know length or mast of ships...nothing...).at my last videos i was using this method(at video i am using the hydro bearings but method works with every bearings...from scope or radar or whatever....) and ,also after i made these videos, Kuikueg released an even more 'comfortable' version of method that simplifies the procedure even more ! have a look at this method ...definetely worths your time !
ps: at videos is NOT showing the use of the BACK side of attack disc(only the front side is showing). if you like to see how to use back side of attack disc for getting target's speed...download the manual called ''Angriffsscheibe_Handbuch_3.pdf'' written by KLH . this is an excellent manual and in there you will see how to use it for getting speed.
ps2:if these tools are not in sh4....what prevents sh4's moders to import them in sh4 ? i am sure that us navy would have similar tools as there were no digital calculators back then. (yes,i know, they had this powerfull radar...which simplified things a lot...)
