Apologies if this has already been suggested somewhere - or if the team already thought of it, but:
As the subject says: can we get some form of passive radar detection, please?
Historically, this has been a feature ... basically everywhere since the introduction of radar.
It doesn't have to be complicated: a single line (even a short one) showing the direction (but not distance or type) to the ship using radar is usually enough. If there are several ships using it, there will be several lines (or perhaps the line gets thicker) - in any case it shouldn't give us anything but the fact there's something emitting over that way.
In any case, it should be available pretty early on, and have greater range than radar - since it's not dependent on the echo for location.
Cheers!

Interesting idea but practically you have to have radar, developed, for it to be successful. So, in the timeline for radar, it would have to follow it. Now, if you have intel on an opponent that has radar, it could be useful. |

Now, if you have intel on an opponent that has radar, it could be useful. Of course - I assumed that was implied: you cannot have passive radar detection if the enemy has no radar (researched, let alone 'fielded' on ships) - the 'early on' part was mostly in relation to radar tech. Also - yeah, that's an excellent addon: you can only use it if you have 'discovered' (through spying or otherwise) the enemy's frequency. Nice one, oldpop2000! |

Another issue, which probably would not be included in the game is the height of the passive radar antenna's. There is a calculation for radar range and height of antenna. It does make a difference. This might be something to add to the ship design when adding radar. horizon distance = 1.25 x square of the antenna height antenna height of 120 feet equals 13.69 miles |

There's already a tech that allows a SigInt report to be created, so this could be a development of the same?

Well, yeah - we already have one for visual observation, after all (which works on the same principle) - I shouldn't imagine an extension of it would be too difficult. |

BTW, there is an effect called tunnelling. It's when the radar signal hits the atmosphere and rides down between two sections. The atmosphere acts like a waveguide. We detected an aircraft once over Tokyo, from Fallon Nevada where our Long range radar was located. Norad finally determined it was tunnelling.
