Any idea of when will the autolock ability be available? It can sometimes make a diference in a dogfight...

What about making your own measures?

I guess with a properly framed screenshot or, even easier, with the VTB viewport feature...

Well the VTB viewport requires both height and width to be set to work, which defeats the purpose. I'll try and judge the size by measuring the HDD on screen.

 

I just wanted to know if the dimesions were well known, I apologize if I sounded entitled or something.

Seems like the best thread to ask: does anyone know what the aspect ratio of the HDD/VTB is? I'm exporting on the second monitor and don't know what the correct height/width would be to have an undistorted image. Thanks!

 

I think the VTB is square, so the aspect ratio would be 1/1

Any news if the radar will be fixed at akk in the next update? The tendency to drop locks, and not allow PIC is a pretty big issue i think.

Is it just me or is close combat mode kinda not working, it doesnt seem to change scan modes unless i 'unlock' (i don`t have anything locked) and it really does seem to pick up almost anything.

 

it was working fine like 1-2 patches ago

I have a question about Mirages radar ...

 

I get it that the radar is Pitch stabilized but is it stabilized for roll?

 

Cus if I turn left or right then the radar contacts are moving on the VTB

 

Can someone explain this?

I have had the same issue, I notice if a target was locked then dropped it will not switch modes so I cycle the RDO and it works again.

 

Just remember all this practice with the radar, acquiring targets and then reacquiring them is going to make us really fast!

I'm aware of the bug and I am trying to find what is the issue. So far no luck :cry:.

 

I'll try to get a fix ASAP.

Yeah the Radar requires some juggling to have it in a functional state but I think I can work around most of the bugs now. The most annoying thing to me is loosing a target in TWS mode :P.

 

Good luck figuring out the solution zues!

I have been doing some investigation on the Mirage as I love the plane and is the only one I'm flying right now.

 

 

Looking at videos I found one that shows some of the radar and HUD,

 

1- Here you can see how the Radar scope looks, I don't know it what mode is but it seems it says on the that only I can figure it out, (CVI or maybe Police? ):

 

Is interesting to see that the TDC does not show the max and min alt of the radar antena.

2- On this it shows how the HUD looks when you have a target locked in PIC mode.

 

 

Look at the distance tape on the right is different on what we have, also I think the size of the flight director ring is a lot bigger. that the one that we have.

Also look at the ALT and speed are still showed at the top

3- On this part it shows how PIC mode is represented in the scope, also really cool when the antena goes over another contact that is no the one locked but cross the line of the emitting antena you see the eco, don't know if this can be modeled in DCS radar functionality.

 

 

 

Is also interesting to see that the TDC on this mode does not show max and min alt at that point and the tracked target show info that I'm not really clear what these are. (20 alt? , 2 Closure rate? )

 

Also if you look at the eco of the second contact further away it has a value that I thing is the closure rate or vector speed?

The other thing I was able to identify is that the scope always show in what mode is on middle top of the radar.

 

 

 

Well I hope this helps the devs!.

 

Thanks.

Probably altitude, and aspect angle (2=20 degrees)

Interesting video! Maybe you want to fix the links, they all point to 24m54s (text is OK but hyperlinks are wrong) :D

 

Fixed, thanks.

1 & 2 are from export aircraft, so RDM radar with different flight director in HUD.

 

Is interesting to see that the TDC does not show the max and min alt of the radar antena.
In fact you have 99 / 99 on the right of TDC. As the flight director shows the target is flying above the aircraft, so the antenna is pointing upward.

 

CWI = Continuous Wave illuminator

It's a feature to guide Super 530D with RDM radar.

I don't know if it means that it's the mode in use or a reminder to turn it on...

 

3) The radar is RDI in PSID (or TWS)

The closure speed is 539kt (539VR), target's altitude is FL257

20 is the aspect angle, like 50 on picture 1

 

Is also interesting to see that the TDC on this mode does not show max and min alt at that point
On the radar panel you can choose between S (site: display max and min alt next to TDC) or Z (average scan zone altitude next to TDC).

Here it seems to be Z mode.

 

Also if you look at the eco of the second contact further away it has a value that I thing is the closure rate or vector speed?

Already included in DCS: closure rate in Mach number.

1) With a lock , the angle of the target apears on the hud - 180 deg. for a head on - and on the radar screen below the target, in this case indicating 0 degr. for a head on, which can be confusing. Why is this difference in the symbology between hud - hdd ? (is there a difference between intercept and aspect angle in general?)

2) Also, with a lock , an arrow extends from the targets marker, indicating his direction, but this line has not always the same lenght. What is the arrow's length indicating ? ( perhaps closure speed ? grater closure speed = larger arrow? is the lenght varying according the selected radar range? )

3) also , at the bottom of the screen there is a big arrow, pointing always at the 12' position and indicating our heading. What is the operational use of this indication? Perhaps, the pilot should put this line in a 90 deg. angle to the big intercept line , to achieve a notch?

1- HUD and HDD target aspect angle are complementary. Don't know why, but it's like that

2- target's arrow length indicates target's speed.

3- your arrow length is proportional to your speed.

I dont know, if this is already asked here:

 

Is the Mirage guiding its semi-actives in SST mode, or does it use another special mode?

It would be great, if there is any possibility to reguide an already launched missile after a SST lock is lost and relocked.

 

I think that this is possible IRL (Radar SAMs are doing it to make it harder for WW to spot the Radar position AFAIK).

 

And why should a semi-active missile at first chase a reflected signal and then ignore it, after there was silent for a few seconds....i mean...as long as a missile is able to receive a target's reflections, shouldnt it go for it?

i was thinking that just the other day, it makes no sense for it not to relock the missile, even IRL.

If the missile loses sight of the target (because of loss of lock) then the target might slip out of its detection cone, in that case it won't be able to reacquire it.

I don't think that detection area is very large.

p. s. I agree in ideal condition it should reacquire

What I mean is that you see another echo from another contact that crossed the beam of the radar.

More likely this is a RDY radar display. RDI requires STT for weapons guidance since the Super 530D is a SARH missile and requires a steady beam for guidance. The RDY was designed to use the more advanced MICA which like the AMRAAM is a fire and forget missile so it can be fired from TWS mode since it can self guide towards the target.

 

Many Mirage 2000 videos show a mix of models, RDM, RDI and RDY. So you cannot take one of them as a single source for designing the RDI interface.

Does that mean, that the s530 is guided by a reflected STT Signal? I think then it should be possible to reguide it after a relock as long as the target is within the receiving cone of the missile. But I wonder how the targets rwr then knows that there is a semi active incoming...
