dutchili Posted March 14, 2023 Posted March 14, 2023 The Viper shows a wrong slant range (99.0) in STT. Additionally the range on the radar is incorrectly set to 120 Nm Steps to reproduce: - lock a target (TMS up) within 40 Nm - Enter STT (TMS up) - Observe how the slant range changes to 99.0 and the radar display changes accordingly - When going back to CRM (TMS down), the correct slant range will show within 2 seconds.

dutchili Posted March 15, 2023 Author Posted March 15, 2023 Here you go. MT, 2D, very reproducable. slant range.trk I go into lock, than stt (slant range goes to 99), back to CRM, back to STT, back to CRM. BTW: is there a location where the last flight is saved? I always forget to save the track...
opps Posted March 15, 2023 Posted March 15, 2023 (edited) Not bug. If you try to STT, target tries to break STT by activating ECM. Radar cannot resolve range(display 99.9 range in HUD) while ECM is in effect until you close in certain range(burn through). Edited March 15, 2023 by opps 1

Burn through range is at around 25-28nm currently, so until then, it will show 99.9
dutchili Posted March 15, 2023 Author Posted March 15, 2023 So the conclusion is that the AI was upgraded and always jamms once locked?
ED Team Lord Vader Posted March 15, 2023 ED Team Posted March 15, 2023 Like @opps said. If the target is jamming, there's no way to figure out the range. This is working as intended. Thanks for your time, nevertheless. Esquadra 701 - DCS Portugal - Discord
enyak Posted March 21, 2023 Posted March 21, 2023 I don't get it. When the FCR is able to maintain STT lock then it is also able to gauge range. Otherwise there is no STT since it relies on accurate range tracking.

This requires range information for accurate tracking, Upon loss of tracking the most the FCR can do is enter a temporary COAST-mode to try and re-acquire the target and regain a STT lock.

You both are correct! abot COAST mode and HOJ! I understand what you are talking about. But ECM was brought up so its worth to mention home on jam as well. Which isn't a thing yet in Dcs F-16, yet! As explained the radar can track a target based on azimuth, because its sees the jamming signal, but the range is unknown. On 3/15/2023 at 7:51 AM, Lord Vader said: Like @opps said.

However you can lock on the target jamming signal known as home on jam "HOJ". The radar is able to see the signal azimuth but the range is unknown Edited March 25, 2023 by TEOMOOSE

The FCR can certainly display azimuth and maybe guesstimated range information of strobers on the scope in RWS mode. However - what you seem to be implying is that the 16 FCR can lock up a jamming target (beyond burn-through range of its FCR) and sustain STT via "HOJ", relying on azimuth information to keep the track alive. Is this correct? I have never ever heard about this capability of the 16 FCR before. If so, I would certainly like to hear how the switchology works and how to select this mode in DCS.

Have you never heard of HOJ ? - i strongly recommend to do some research on that. Its not aircraft specific, its a radar feature on all if not, most an/apg radars.

Sure! You may have your own sensor radar burn through his jamming signal. Therefore Azimuth and range is calculated. However beyond that "burn through" range your radar cant calculate range, but you know his azimuth. If theres an awacs he/she can provide you with range information. So if you call strobe North, they say: strobe range 45, TWENTY-FIVE THOUSAND, hot, hostile. Therefore you the pilot assess shoot criteria and act accordingly. However HOJ is not implemented and currently you cant lock on strobe, jamming targets. Theres no guesstimated range information of strobers! If radar within the burn through range it will show you that contact is jamming but at the same time it can calculate range as well. Azimuth and altitude is always known.
