I have used the FFG radar extensively and I have to say it works properly.
It detects contacts in appropiate ranges but sometimes it takes time to do so.
What you really have on DW is not a radar screen operator, what you get on the Wapons Coordinator Station is the already procesed radar signal that have been collected and "analized" on the Radar Station (not existing in Dangerous Waters FFG)
Radar retourns are not showed up automatically on the screen, it takes time, first to radiate enough to collect energy retourns and then some computers analyze those information and discriminate from others non relevant so actually what you can see in your "radar screen" is "old information", maybe 5 or even 10 seconds old.
Radar here does not work as a temporary "show true" but it is modelled the way it works on warships at some extend.
I have realized that the radar picks up very well missiles that fly high or that when launched they made a high trajectory but on the other hand if the skimmer has been all the way low, you will pick it up on surface radar when it is almost too late.
If you suspect Vampires imbound, activate the CIWS to Auto.
One of the most dificult choices of a FFG driver is when to go ENCOM or not, sometimes your radar will give you away and will give you no information in exchange, other times it will help you to win the match.
Experience and a good intel on the threat will tell you when to use it or not.
