Might be the bar count. ECRS has a lot more.
how is it impossibly fast?
Bar count and elevation limits. ECRS is scanning a significantly larger area
The scan rate as it stands is nearly identical (they both sit in the 190~195 range)
how do the bars work? how is the actual scan speed derived from that?
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?
“Gaijin doesn’t accept reports based on calculations” (I know)
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
