Professional Radar

[Richard Webb 1097731]

Just wondering if anyone has done any kind of tutorial video on what professional radar is and how it works? It seems pretty cool, but it sounds over the top as far as complexity to set up and use. Maybe I'm just not understanding it completely.

I am not aware of any tutorial video on that, no.

 

If there are any specific parts of the wiki that could use some clarification, ask for it. But it needs to be specific

[Todor Atanasov 878664]

As Stephan pointed out, there is no video tutorial, and frankly there is nothing so complicated in that mode. All you need is to define some radar stations, if you need radar holes, set the mode in the display settings and chose one of the correlation mode in the general settings.

[Luke Cunningham]

How do you define the radar stations, Todor?

[Todor Atanasov 878664]

Read the wiki for the ESE file, RADAR subsection. There you will find everything you are looking for => http://euroscope.hu/mediawiki/index.php?title=ESE_Files_Description

[Luke Cunningham]

Is this correct?

 

[RADAR]

RADAR:Clee Hill:N052.23.53.090:W002.35.55.510:0:0:0:90:50:40:90:50:40

 

Or, is this..

There is no primary radar situated on the Clee Hill site, it is secondary only.

This one.

[Luke Cunningham]

Thanks Todor,

 

Myself, Mike Pike and James Latham spent some time yesterday evening working out some digits to use based on real world data. It works a treat.

 

Thanks very much, all.

[Luke Cunningham]

Now, I've come to set up the surface movement radar however, all surface movement radars point down at the the floor so, in effect it is an inverted slope.

 

Will ES recognise negative numbers e.g. 2:-30:25

 

Or is there another way?

[Halldor Bui Jonsson]

what digits did you arrive to and how did you determin them? Would love to know the forumlas needed (for slope?) if you have known radar with elevation, lat/long + range.

[Luke Cunningham]

Hi Haldor,

 

First you need to understand which radar head you need to use, its elevation and theoretical range. I got these from our aviation authrority and a real world controller in the UK division.

 

If you can find those, I'd be happy to help you.

Here are the radar sites i want to do:

 

Radar Site H-1

Type: AN/FPS-117 v5 Phased Array Search Radar (PSR+SSR for VATSIM purpouses)

Location:64°1'17"N 22°39'23"W

Elevation: 173ft

Theoretical Range: 215nm at FL300 (SSR) 60nm PSR

C mode

 

Radar Site H-2

6609N 1505W

Elevation 2359ft

PSR60nm+SSR 230nm C mode

 

Radar Site H-3

6415N 1500W

Elevation 10ft

PSR60nm+SSR230nm C mode + ADS-B (S mode?)

 

Radar Site H-4

Type: PSR+SSR (C mode)

Location: 6611N 2319W

Elevation 2041ft

Theoretical Range at FL300: 235nm

 

Radar Site Akureyri PSR

N065.39.18.297:W018.04.26.251

Elevation 40ft

PSR 60nm (this ones in a valley though, need to find out how to simulate that).

[Martin Loxbo]

ADS-B (S mode?)

Well, ADS-B does not equal mode S, but ADS-B can be simulated via a plugin, if you decide that all aircraft with a certain equipment suffix, a certain flight plan remark, or even a certain aircraft type will be considered to be ADS-B equipped.

 

Regarding the slope, according to the Wiki: "This a linear slope that levels the visibility floor up by the distance. The value itself is the feet to be climbed in one NM. I used value 60 that levels the visibility floor from 2000ft to 11000 at 150 NM away."

 

We have set the slope value to 30 in Sweden and it seems to be fairly realistic. Of course a higher value will decrease the radar coverage at low levels significantly.

[Todor Atanasov 878664]

Now, I've come to set up the surface movement radar however, all surface movement radars point down at the the floor so, in effect it is an inverted slope.

 

Will ES recognise negative numbers e.g. 2:-30:25

 

Or is there another way?

Why do you want to use a negative slope?

[Halldor Bui Jonsson]

ADS-B (S mode?)

How would ADS-B correalate to VATSIM via plugin, same functioning as S mode per se?

 

Would it be better to set up a seperate PSR radar with its own linear slope, rather then shared with a SSR radar that needs to cover different ranges?

 

Is there any limit on the number of radar sites one can set up?

If the PSR is in one axe with the rest, I don't see why you would do that.

RADAR:<name>:<longitude>:<latitude>:<P range>:<P floor>:<P slope>:<S range>:<S floor>:<S slope><C range>:<C floor>:<C slope>

That means that you can have PSR + SSR(mode A + C) + SSR (mode S) in one line, and all will have different floor, slope and range.

 

There is no limit on the radar number definitions, but you wouldn't need too much anyway

[Luke Cunningham]

Now, I've come to set up the surface movement radar however, all surface movement radars point down at the the floor so, in effect it is an inverted slope.

Or is there another way?

Why do you want to use a negative slope?

 

Because I want to use my SMR File on the Ground with Radar mode, but I need to define a radar? Hence, a Surface Movement Radar

 

All surface movement radars point down at the floor so would require a negative slope.

[Todor Atanasov 878664]

I know how it is in reality, but you don't need to do that (the slope actually is not negative, it is simply wide in vertical plane). Simply add a radar station, with floor the APT elevation, set your range and then simply make the slope very low. If you want to simulate the radar "blind" spot, just below the antenna, add a radar hole, around the radar site, with width let say 100 meters (you can do that quite easily using the .sline command in ES, drawing the hole and then coping the coordinates)

[Halldor Bui Jonsson]

How would you define a hole for something like a mountain?

[Todor Atanasov 878664]

Like that

You define the hole to match the top picture's filled object. And then add the altitude from the second picture. Just one note, the hole is for all radars, so if you have multiple radar coverage, the figure's shape changes

[Halldor Bui Jonsson]

So the hole defined will affect all defined radars regardless of their position?

[Todor Atanasov 878664]

Yes

[Halldor Bui Jonsson]

Luke, what numbers did you arrive to and what formula did you use to determine them?

[Luke Cunningham]

The numbers I have were from a real world controller who gave me some details about the radar station he has from his docomeentation. No forumla required really. Depends on the radar station.
