State of the Current Radar

[cauldron]

Lets have a thread about the Radar Only: All goes as long as its about the Radar.

 

 

 

I have some questions, since lines and azimuth are working as well as range scale/cut off, and I already know antenna steering is not working; so this leads me to several questions:

 

1. Is the Antenna scan lines & azimuth respective to the Mirage's attitude or the Horizon? What happens when you roll the plane? What about beyond 90 degrees?

 

2. In 2.0 i tested TWS/PID mode and found it lost a PID-track at +/- 30deg elevation and were within 10deg azimuth respect to the nose of the plane approx. is this normal?

 

3. Also, I have noted that the radar seems to detect in RWS mode objects excellently at long range, but targets within 10NM straight in front seem to not be lockable to PID nor PIC modes. But if you switch to CQB modes it locks them up nicely... these are non maneuvering Ai test planes i set up. Anyone have an idea?

1) Unlike FC3 aircraft, the Mirage's radar is actually attached to the virtual aircraft. As such, pitching the nose up points the whole radar scan zone up and rolling to the side causes the radar's scan zone to roll with you.

 

2) Not sure off hand what the scan zone limits are, but +- 10 deg is about what I've found them to be in the vertical (relative to aircraft). As an interesting side note, rolling to the side is a pretty decent way to pick up contacts far above or below you. Just be careful to lock them prior to rolling upright as they will be a ghost contact the instant your aircraft rolls or changes direction.

 

3) I haven't had any issues, but as said, both aircraft must remain very still at such short distances. Any pitching or rolling on your part can make even a fresh contact a ghost contact. Reducing the scan zone helps a lot here. I recommend 15 deg sweep for close quarters, anything more than that updates too slowly to be of use.

Real radars address stabilized with respect to the horizon, and will alter the raster as required to maintain that.

 

The FC3 jets represent this correctly.

I guess it will be the same on the Mirage once the Radar become movable. If we had that today, we would be not able to find targets way below us if we pitch down or the opposite.

The Radar can scan only 12 deg vertically when you have 4 bars. In the beta it is by default 4 bars and it is not changeable. in the future you can move vertically the radar to cover 60 degrees with those 4 bars (12 deg)

Wouldn't you just decease the range (For a better view of contacts on the scope) and point the antenna down (Or up)? You'd get better results than with a small pitch I'd imagine.

Are you serious? I've been putting my Flanker in all kinds of angles, hoping to detect targets better by pointing my nose in different directions, but this doesn't help with FC3 aircraft?

Oh wow...

for sure, but currently the radar doesnt go up and down, it will come in a future update. the only solution now is to point up and down with the nose like you do with the MIG21. The radar of the Mirage is much less sensitive to the ground clutter.

Mhm, due to Doppler's gizmomatic clutter filters.

 

Also, I should have been more specific. I meant when it can move later on (Hopefully sooner is the new later), so for now it's the MiG Radar shuffle.

 

I just really want to finish moving so I can fly this thing again. Only managed to get an hour in so far.

Do you know what happens when you roll to 90deg or past 90deg? Specify if fc3 craft or M2000 thanks ;)

Zeus mentioned it is actually working in Beta.

 

Azimuth and bars work. What is not working is moving the antenna manually.

I know what happens with a real radar, and I know that FC3 aircraft represent this correctly for the radar sets that they simulate.

 

I expect the M2K to be made to work the same way, since it is of similar technology and philosophy.

 

In other words, the scan should be stabilized on the horizon - as you're rolling the radar will adjust the scan.

 

Things like AACQ modes are going to be stabilized on aircraft boresight typically, so moving the nose moves where the radar is looking.

Adjust as in the dish will stabilize on the horizon, or will shift it's scan with the roll? In the MiG-21 the radar dish self stabilized up to 60* bank, hard to believe it would be any different in that regard. Currently it doesn't work that way on the Mirage, but just curious

[Zomba]

Just to add a little to the topic: The Mig-21 radar is stabilized to horizon within certain limits.

 

~70 degree roll and -8/+25 degree pitch. AFAIK stabilization is fairly common with fighters.

Scan is shifted with respect to the aircraft's plane. The scan is assigned with the horizon, not with the bank.
