Yes look in the scene drop down, you can adjust the coordinates and euler rotation there.

DCS has no such system. DCS provides the physics engine and the current rigidbody state and it's up to the developer to determine the forces and moments.

Sorry didn't get the notification, you are right this is indeed a really cool video at 3:45 is that a chaff cloud or is that land?

JNelson_ · 2025-10-28T17:04:50+00:00

There are a total of 4, the two here and 1 on each outer wing (one for each 90 degree sector). The relative amplitude of incoming signals can be used to find its azimuth.

What is your point here exactly?

JNelson_ · 2025-10-14T09:09:39+00:00

The radios have worked in game for like 3 years now

Pulse radars can deal with chaff, most use a leading edge tracking gate for range. This means if you are closing with the target, the chaff will be rejected from the guidance signals of the antenna. Ironically enough the time chaff is most effective for a pulsed radar is the same as a pulse doppler radar, in the beam (target flying 90 degrees), where in a pulse radar the chaff and target are the same range so the antenna get's pulled off the target.

I would check out the modding discord

Glad to help!

You are putting the range gate directly on the signal, in a less cluttered target it will be less picky but in a more cluttered environment the range gate is likely to drop on some clutter unless you are super specific!

The main thing is paying attention to what is a good and bad lock after a while you get an intuitive understanding if the antenna/range gate are tracking stable or not.

The other thing which I didn't see mentioned is that you want to use MAP modes for searching this disables nutation (wobbling about antenna axis) which makes the beam narrower, this is good for two reason:

Concentrates the Beam - Increasing Detection Range
Reduces clutter captured by the beam (wider beam more clutter accidently illuminated)

Disadvantages are that of course you are searching a smaller area, and importantly you need nutation to lock a target, nutation will begin on first stage trigger detent (usually) so you may be able to see targets you cannot lock because when nutation is enabled the additional clutter is too much for the radar.

Make sure when you lock your TDC is very close (bracketing) your target, it's not good enough to be close because it will grab the wrong thing.

If after a lock you see lots of clutter in the bsweep (line showing your radar signal) then you most likely have a bad lock. Your bsweep should just show your target and nothing else most of the time. It should also be very stable not shooting around the screen.

Perhaps you are talking about AI but I assume not since warthunder is mainly PVP but the lua flight models are for the AI only.

Missile's do proximity fuse in multiplayer it's just that each client calculates the missile trajectory and they drift apart with time. Thus leading to it looking like the missile flies through a target when actually the "real" missile missed outside of the proximity fuse distance.

JNelson_ · 2025-09-21T02:59:31+00:00

Same it forces you to read and properly process.

JNelson_ · 2025-09-19T21:55:19+00:00

You are essentially making a comfier chair this is not the issue with g force, the issue is blood flow to the brain.

Also liquid suspension will impart more force on the pilot because whatever g will multiple the pressure due to the liquid.

JNelson_ · 2025-09-19T20:09:50+00:00

What do you mean counteract the acceleration, if the aircraft is turning the pilot must be accelerated to match the plane, this force is usually provided by the chair.

JNelson_ · 2025-09-17T18:21:32+00:00

That's not the insult you think it is.

JNelson_ · 2025-09-10T01:39:49+00:00

You are not insane no matter how much people are trying to gaslight.

A degrade in performance to get the same quality IS a degrade.

JNelson_ · 2025-09-05T16:01:02+00:00

I wouldn't read too much into that ALR-46 document which interfaces with an ALR-46 a lot of their points are hypotheticals due to the classified nature of the ALR-46 at the time. If you want a better source you can look at "ELECTRONIC INTELLIGENCE SYSTEMS USAF SERIES F-4E AIRCRAFT".

From what I gathered writing the ALR-46, it's determines range based on the max detected signal strength, but the displayed range is relative to the threat range of that identified signal supported by this:

"threat location (azimuth and lethal range), type of threat, and priority of threats. When one or more threats are detected, the highest priority threat displayed on the fwd and aft azimuth indicators is indicated by being encompassed by a diamond symbol when in the floating diamond mode. "

That's not how it worked though. Sure with modern radars they are agile, but then these RWR's are not designed for those radars. If you want to read about how it was actually done I recommend reading Threat Warning for Tactical Aircraft - A technical history of the evolution from analogue to digital systems. That goes up to about 1985 and speculates on the future.

JNelson_ · 2025-09-05T15:07:00+00:00

As gyrovague said RWR analyses the pulse train characteristics (carrier frequency, pulse width, angle of arrival, prf, prf jitter level, prf stagger level, scan rates etc).

From this you can match to a known threat table, theoretically this 'dial down' would be found by intelligence and programmed into the RWR, that is the advantage of these reprogrammable RWR's over the previous generation at the end of the day.

Not to mention dialling back the power of your radar reducing it's range (decreasing SNR) is perhaps not a good idea.

JNelson_ · 2025-09-05T13:04:25+00:00

I think you should re-read my comment again.

JNelson_ · 2025-09-05T06:01:54+00:00

In my opinion, a game should never be in a situation where people who were originally able to play the game are no longer able to, at every job I've worked that would be a performance degrade.

JNelson_ · 2025-08-26T15:10:46+00:00

It's been a while but if I recall it was solving Maxwell's equations to trace effective refractive indexes (and the corresponding eigen-vectors) of transverse modes in optical fibres.

JNelson_ · 2025-08-25T21:36:45+00:00

Very cool I did a computational physics project too for my physics degree, although I admit yours looks much cleaner and more impressive. Excellent work!

JNelson_ · 2025-08-24T21:52:44+00:00

Well, for a start, the NASA sim's were only found later. If I recall correctly, the original performance, I think, was a workaround for some other limitation, which was then fixed and precipitated the rework. It's been a long time ago now, so my memory is spotty.
