RWS DTT and TWS DTT - Any Diff ?

[GrEaSeLiTeNiN]

Are there any fundamental differences between RWS DTT and TWS DTT? Apart from slight differences in azimuth and bar scans, they look to be doing the same thing. Or does RWS alert the bugged targets in their RWR while TWS only alerts them when the missile has gone active?

They both alert targets the same. 
 

My POV is, RWS is very customizable, you can change bars and azimuth as much as you want if target is far enough away. This makes it good for searching just they way you want. The fact that it shows bricks instead of processed tracks also indicates a lower amount of processing which I’m sure helps in the real world to find targets. 
 

Becuase of it going 15 degree azimuth below a certain range, that seems to make it more optimized for locking one target at once even though it can do two. 
 

Also, if you calculate sweep time, azimuth, and bars, in TWS no matter the setting the time between the radar contact being updated is more consistent, between 1.2 seconds and 4 seconds. While in RWS this can be much longer or shorter update depending on setting, anywhere from .5 seconds to 8 seconds. This more consistent update time is likely optimized to provide reliable updates for missile guidance, so that in battle no matter your setting in TWS the missile receives just as much midcourse update as any other TWS setting. 
 

A lot of people will say RWS is good for searching and single target track even if it CAN do more, while TWS provides more consistent missile updates for two target attack. IRL becuase of less processing RWS is said to be far more reliable then TWS. 
 

In my experience for final attack with two missiles, I always use TWS. That way my azimuth doesn’t change in me within a certain range and my missiles get reliable updates.

One other factor that makes TWS less reliable IRL but perhaps better for missile attack, is the bars in TWS overlap less then the bars in RWS. This means that TWS has a larger vertical degree of coverage then RWS given the same bars, but it’s then also less likely that a targets change in course will be detected by successive bars in TWS. I dont think this makes any practical difference in DCS other then the change In Elevation coverage. I think RWS bars overlap 1.7 degrees and TWS bars overlap 1.4 degrees.

Found post explaining bar spacing, it’s actually 1.6 degrees for TWS and 1.3 degrees for RWS https://forums.eagle.ru/topic/230892-targeting-pod-and-scan-bar/?do=findComment&comment=4238245

Hey thanks for the detailed POV.  I just realised I asked a similar question a year ago, lol.

I saw that! I do the same. It’s understandable

one thing that is obvious, at least to me, is that all the other contacts on the radar show bricks in RWS but on TWS they show vectors...
