Some great information here.

The AWG-9 Air Superiority Weapon Control System booklet listed here *might* be

The AWG-9 Air Superiority Weapon Control System Report No. PMSE-240/2174, Hughes Aircraft Company (Confidential)

Which is potentially pretty interesting. Anyone in Las Vegas area could try to check it out.

Range is different from range. That's why I tried to specify details for those numbers. As for what tech should've given it better detection range? It's ESA, thus have quite a bit narrower beams giving it better power to return ratio. It has quite healthy dig processing (despite your bashing of Argon-15A which I tbh not totally understand). It IS quite powerful (don't have specific tube info, but N011M have 8kw tube with ~5kw peak while having 1.2kw average, so it's not just ×2). BTW on N011 example - M has better range chars despite having less peak power than slotted 011. ESA matters.

Plus, Argon-15 matters too. According to 'Авиация ПВО России и научно-технический прогресс' written by Academica E.A.Fedosov, Zaslon implemented Wald Test (some kind of likelihood estimation?) in target detection, which is classified as 'advance' in the well-known 'Introduction'. This means, with same returning power, it could decide is it target or not way better than the traditional single threshold method.

Anyone know how accurate is this tibit ?

Human-step-in literally means guess-it-or-not, most unreliable.

Hmmm... Isn't 200km was instrumental range for whole AWG-9?

Yes, 200 but not km , nmi ( 370km) and it was in TWS mode.

According to the famous test from 1973 ,it was achieved in the TWS mode when F-14A flying 1.5 Mach at 44000 feet with its AN/AWG-9 tracked incoming USN BQM-34E 'Firebee II' flying 1.5 Mach at 50000 feet from 132 nmi ( 244km) away. Launch range of AIM-54A was 110 nmi ( 203km ). Detection distance was maybe even greater ? Question ,BQM-34E had frontal RCS of how many sqm? Couldn't find but there is some data about BQM-34A 's RCS .

For comparison ,radars like AN/APG-63/70 in the Eagles and AN/APG-68 in the Fighting Falcons have max detection ranges in TWS 80nmi ( 150km). Radar AI.24 called Foxhunter in the Tornado ADV F.3 has max detection range in TWS 100 nmi.

Data like this are simply wrong :
