Remember that YOUR AOB to the target...aka how much aspect you show him...aka ..how much of your sub you expose is a factor too (in think anyway)..... if you are ever worried about being seen...the first step is to go nose on or tail on the target to "get skinny" and make it harder to see you. Calm seas are Bad!! excessive speed...is bad...as you would have a bigger bow wave. moon between you and the target is bad. ...now to anwser your question....I dont know how much of these factors are incorporated into SH5....looking at the date cfg file might be a start.......

from SH5/data/ctg/sensors.....visual..

Visual range factor=0.30 ;[>=0] was 0.5, decreased by 25%
Visual fog factor=0.75 ;[>=0]
Visual light factor=1 ;[>=0]
Visual waves factor=0.65 ;[>=0] was 0.8, decreased by 25%
Visual speed factor=0 ;[>=0]
Visual aspect=0.9 ;[>=0]
Visual enemy speed=0.2 ;[>=0]
Visual noise factor=0 ;[>=0]
Visual sensor height factor=0.5 ;[>=0]
Visual already tracking modifier=600 ;[detection probability modifier], most accurate, once a contact is detected it will lose it very hard
Visual decay time=250 ;[>0] already tracking bonus decay, in seconds
Visual uses crew efficiency=false ;[true or false]

So.....light is the biggest factor .....followed by aspec, fog, waves, range, then enemy speed..... I think this is for both friendly and enemy AI. currious that speed factor is 0.
