You have to be in visual range, or radar range if you have one, which is the horizon plus a bit more depending how high above sea level your are and how tall your target is.
If you’re on a ship, unless you’re using an advanced radar that bounces signals against the ionosphere or you have a meteorological phenomena called an inversion which can curve your radar energy over the horizon a little bit, your radar horizon is surprisingly short, something around 12 nautical miles give or take. And the sea is big and Iran is quite far.
This is one big reason why aircraft are used for surveillance at sea. They can go much higher than any ship’s radar antenna mast every could be which significantly expands their radar horizon. They can also scan a huge area relatively quickly as they can travel much faster.
Because if this fuck up, Iran now has the intel that the French carrier is approaching without even having to send an aircraft out to look for it. If they even still have the ability to do so at this point.
The Swedish Navy’s ships do have some bonkers designs, like massive barcodes printed on the side. It’s so that when they get back to port they can scan the navy in.

why don’t ships at sea simply disguise themselves as a rock or shrubbery?
Or as a duck if they need to move.
BTW sweden have some cool ship disguises.
Edit: went looking for it, couldn’t even find a photo.
Yeah, that’s how good they are.
Found an old, not very effective but fun one:

(‘scandinavian’ for people like me)
China and Russia could also just tell Iran, if they don’t have satellites of their own
It wasn’t exactly a secret, France publicly announced it was being moved to the eastern med
