ebabil Posted September 22, 2020 Share Posted September 22, 2020 Hornet is my first plane that has AG radar. And I have learned that I have to approach target area with some angle (like 25 or something). Otherwise radar can not illuminate the area Is this the fact that every plane has to do that? For example I don't have Viggen and JF17. Do these plane have similar radar tech? Will viper the same?

Northstar98 Posted September 22, 2020 Share Posted September 22, 2020 (edited) As I understand it, you only need an offset in the Hornet for the DBS modes, the Viggen doesn't have any, you just get the 'map' without any of the expand modes or anything. Heatblur's Viggen I think uses a different technique to simulate its RADAR, compared to the Hornet (Viggen uses raycasting(?) which I'm pretty sure is different to how the Hornet is simulated). So far (testing w. current 2.5.6 stable), I can make out way more terrain details in the Viggen, with more clarity, than I can in the Hornet. (Not sure if this is realistic or not). For instance, in the Viggen at short range (<15km), I can distinctly see pylons, rivers, bridges, airfields and trees. In the Hornet though, the only thing I can really see are clustered buildings and roads (which seem to show up really well), I can't really distinguish anything else apart from where the more obvious hills are. You can up the gain, but it just seems to make a mess, especially if there's more buildings around. Obviously in both it's super obvious to see coastlines and ships (though Viggen is better at it at the moment, but then it's designed to pick up ships). Things might've changed with the OB AG RADAR for the Hornet though, but not sure to what degree.

Flagrum Posted September 23, 2020 Share Posted September 23, 2020 The Viggen I think uses a different technique to the Hornet (Viggen uses raycasting(?) which I'm pretty sure is different to what the Hornet does). I don't know the exact differences between how the real Viggen radar works and how the real Hornet radar works. But the term "raycasting" refers to the software technology used to simulate the Viggen radar in DCS, it has nothing to do with the real Viggen. I don't know the details, but raycasting is probably trying to replicate to some extend how radar waves work in RL. It projects/casts a virtual "beam" to one point on the ground and if that beam intersects with either an object or the ground, it is represented on the radar screen visually as some sort of "radar return". Then the next beam ist cast to the next point on the ground, etc. until all points that are within the radar limits are tested. Link to comment Share on other sites More sharing options...

Yes, that's exactly what I meant, I'll edit for clarity. The point I was trying to make is that Heatblur (and now the MiG-21bis as well, but WIP) AFAIK use raycasting technology in their modules, leading to potentially more accurate depictions (you can see this in the F-14 when picking up ground clutter in pulse search, compared to the F-5E for instance, which seems simplified).

ebabil Posted September 23, 2020 Author Share Posted September 23, 2020 Here what I want to learn is, Do real Viggen pilots have to apporach offset and Do DCS Viggen pilots have to apporach offset? Do real JF17 pilots have to apporach offset and Do DCS JF17 pilots have to apporach offset?

kengou Posted September 23, 2020 Share Posted September 23, 2020 Here what I want to learn is, Do real Viggen pilots have to apporach offset and Do DCS Viggen pilots have to apporach offset? Do real JF17 pilots have to apporach offset and Do DCS JF17 pilots have to apporach offset? My understanding is that the offset required is only a limitation of the way Doppler Beam Sharpening works. The Viggen has no DBS so it has no problem with radar mapping across its entire field of view (just like the Hornet's in normal mode). The JF-17 and F-16 have different radars than the Hornet so I can't speak to how they are supposed to work in reality.

Northstar98 Posted September 24, 2020 Share Posted September 24, 2020 Here what I want to learn is, Do real Viggen pilots have to apporach offset and Do DCS Viggen pilots have to apporach offset? No, the offset comes from doppler beam sharpening, used to refine the resolution in a RADAR expand mode (or whatever equivalent), the Viggen doesn't have this mode available (you just get the basic AG RADAR display). Do real JF17 pilots have to apporach offset and Do DCS JF17 pilots have to apporach offset? I don't have the JF-17, but I imagine it works identical to the Hornet, i.e no offset required for the basic AG RADAR mode, but one required when using DBS in an expand mode (or whatever the JF-17 calls it).
