exnihilodub Posted February 25, 2017 Share Posted February 25, 2017 Hi. I've read the manual and it says the passive scan mode returns jamming signals. Is that the real-world functionality of that feature? Wouldn't it also return some signal if someone was actively locking me up (a SAM site for example)? I apologize if this is a noobish question, I don't know how exactly the radar systems work in real life but i was just wondering. I thought the passive scan is just like a more accurate RWR. Thank you all Link to comment Share on other sites More sharing options...
JanTelefon Posted February 25, 2017 Share Posted February 25, 2017 As far as I know the passive mode will return any radar echo it encounters. I think that means both jamming signals and signals such as search radars. I'm almost certain, but it would be good to have it confirmed by someone else. I suppose it's easy enough to test. Set up a mission with a bunch of different radars at different locations and point the passive scanning nose at them. :) Link to comment Share on other sites More sharing options...
renhanxue Posted February 25, 2017 Share Posted February 25, 2017 I think you're misunderstanding how it works. The passive scan mode is, as far as I can tell, exactly like the regular active radar, only without the actual transmission from the antenna. Another Viggen's radar emissions might show up, but that's the extent of it. Air search radars and things like AA missile targeting radars are very unlikely to have the same frequency and PRF as the Viggen's radar. Link to comment Share on other sites More sharing options...
JanTelefon Posted February 26, 2017 Share Posted February 26, 2017 I recall seing black streaks on the radar with it in passive mode. These streaks would come roughly from a known ship location of a ship. I don't know for sure if it's from a search radar or a jammer. Link to comment Share on other sites More sharing options...
