Eurofighter Typhoon (UK versions) - Technical data and discussion (Part 2)

I have no idea, I could never get my head round the bars and stuff

I like flanker chan as much as any other guy, but you cannot take his calculations as fact. his calculations change over time. just look at his rcs sims for example

Scan speed is (width*2)/(period/barcount) iirc

To clarify this, it is not 30, it is 60 wide, you have to multiply it by 2.
Next is bar count, it is different, irbis has 4 bars, ECRS 12.
If do the simple math of scan width (60)*bars, and then we divide it by the scan rate, we get
196 degree/s for Irbis
184 degree/s for ECRS.

Sure but that’s a matter of margin of error. The probability of being out by a factor of 2 (90.5 vs 195) is… immensely low. Even if you assume some assumed numbers are wrong.

he’s just a guy on the internet lmao, he’s not a proper source.

the 200km range in question:

So does that mean that Irbis, a friggin PESA, radar really scans faster than the ECRS AESA radar.

Also, what is a bar?

ECRS is underperforming considerably in all but the 200/180 modes. Should be like 560+ Deg/s in the mode you are comparing. But Gaijin wont set a scan speed per mode for some reason, so all are set to the slowest speed

The green area is acquisition region. It can TWS targets far beyond that (out to the full 350km it claims). The cause of the acquisition region being small is the geniuses at gaijin entertainment made the acquisition pattern use MPRF which cuts its range down to 150 lol

The radar does not scan it’s whole elevation at once (in this case), it splits it into bars, they are horizontal lines, that the radar scans around

You can see that Irbis scans 5 bars, per a single cycle, while ECRS scans 12.

On the topic of bars has mythicpi updated the radar spreadsheet with the nerfed scan speed yet

Don’t think so

I see. And so why should that make a radar slower or faster. Shouldnt a radar that sweeps x degrees per second sweep y bars simply in x degrees per second regardless of what number y is?

To clarify. I though sweep speed was simply its “horizontal” sweep speed

you cant launch at those targets, because the game wont let you softlock them

Spoiler


in the images it softlocks a target at slightly over 160km and its not in a HPRF mode bc then you would see this in the HUD:

hypothetically if you have a radar that can scan 35° per second and you have a scan patternt that is 70° x 5 bars, then it would take that radar 10 seconds to complete the scan pattern

Well there’s other reasons why you can’t launch at the targets 160km out…

So. All of this is totally up to gaijin unless proven otherwise, and it was their choice to make the ECRS slower.

You’d think a primary source would count as “proven otherwise”
