It has by FAR the largest TWS scan volume, at 70x31 deg, with vertical scan area being of higher value than azimuth, since vertical target position is much harder to determine than target azimuth.
We can do some comparisons tho, taking RBE2-AA, V004 (Su-34 PESA radar) and CAPTOR-M.
TWS Narrow:
CAPTOR-M: 20x4.2 deg / Period: 0.6s / Scan rate: 66.67 deg/s / Update rate: When scanned
V004: 30x10 deg / Period 0.92s / Scan rate: 130.43 deg/s / Update rate: 0.01s
RBE2-AA: 30x15.75 deg / Period: 1.7s / Scan rate: 123.53 deg/s / Update rate: 0.01s
TWS Medium:
CAPTOR-M: 60x8.4 deg / Period: 3.7s / Scan rate: 64.86 deg/s / Update rate: When scanned
V004: 60x10 deg / Period 1.85s / Scan rate: 129.73 deg/s/ Update rate: 0.01s
RBE2-AA: 70x15.75 deg / Period: 3.96s / Scan rate: 123.74 deg/s / Update rate: 0.01s
TWS Wide:
CAPTOR-M: 140x4.2 deg / Period: 4.3s / Scan rate: 65.12 deg/s / Update rate: When scanned
V004: 60x20 deg / Period 3.69s / Scan rate: 130.01 deg/s / Update rate: 0.01s
RBE2-AA: 70x31.5 deg / Period: 7.92s / Scan rate: 123.74 deg/s / Update rate: 0.01s
So;
- V004 is the fastest scanning with an average scan rate of 130.06 deg/s (5% faster than RBE2-AA, 98.4% faster than CAPTOR-M)
- RBE2-AA has the highest scan volumes (57.5/83.75/83.75% larger than V004, 462.5/118.75/275% larger than CAPTOR-M)
- RBE2-AA and V004 update tracks so much faster than all mech scan radars in-game its pointless to even bother putting into numbers.
V004 might search marginally faster than the RBE2-AA (a 5% increase in time to first find a target is basically nothing), but the RBE2-AA scans a MUCH larger area of sky than any other airborne radar in-game on top tier jets.
As for the comment about range. Range is irrelevant. Map sizes are at most 126x126km in-game, airfields are usually within ~100km of each other, and engagements almost never occur beyond 50km, and that’s pushing it. The RBE2-AA has more than enough lock range for all engagements in-game.
To add to this, your comment comparing the RBE2-AA’s time to find a target compared to the CAPTOR-M is an absolute joke. The CAPTOR-M’s only useable TWS mode for searching is its medium pattern (60x8.4 deg, 3.7s period), this is roughly equivalent in search area to the RBE2-AA’s narrow search but trades elevation coverage (the most important part) for azimuth coverage, and takes about 2x as long to search the area. The narrow scan is utter trash for anything but a TWS track, and even then its basically no longer a TWS lock, its more of an STT but less solid in exchange for not triggering a lock warning. The wide scan is also effectively worthless, since it scans so slowly and is only scanning a narrow band of sky which is almost entirely pointless. EFT pilots constantly have to micromanage radar altitude to try to find targets, and often times have to abort BVR engagement because they did not find the target on time, an issue the RBE2-AA would just about never have. Trying to compare them is a bad joke and just shows how little you understand of how good the RBE2-AA is in-game as a radar.
