I found a message on the Chinese website that someone sent an unpacking message saying that the .38 version will fix CAPTOR-M, do you have any news about this
好像只改了irst，雷达没修，bvvd真司马了
It seems that only the IRST was fixed, and the radar was not repaired.
I can’t find any indication that the Eurofighter MAWS is AESA - nor any indication that it is L band. All I can find is that it is active, all three sensors are radar based and must have some form of emission at all times if it wishes to see incoming missiles.
Does anyone have pictures of the sensors themselves without a cover?
This appears to be the system used on the Eurofighter part for part; Source
The components for the active MAW are almost identical;
Flame has a report stating that the MAWS should have accurate prediction of time until impact for incoming ordnance - citing the aforementioned source afaik.

The distance and speed can be found, but the specific angle of attack for the incoming munition cannot. These are three wide-beam antenna that each need to cover at least 120 degrees for full lateral coverage.

The rear sensor alone is trying to cover a full 180 degrees;

As seen in any papers covering active MAWS, a wide-beam antenna is required to have the full coverage required of a MAWS. This means it will have poor measurement of missile angle-of-arrival as stated; Source
That is not the missile approach warner.

Additionally, the Eurofighter’s DASS system will be emitting large amounts of radiation likely in L-band that modern Flankers such as the Su-35 are specifically designed to pick up and hone-in on.
This defense suite may actually be the undoing of a Eurofighter in modern air combat against the aircraft it was designed to fight. @BBCRF Any thoughts on that?
The eurofighter MAWS operates in the Ka-band.
Happen to have a source for it?
Well it must be some type of ESA (and lets be honest, the difference between the PESA and AESA at this antenna size is basically academical). The modules in the wingroots are certainly no mech scan (so its extremely doubtful that the rear one is), and a fixed antenna would require ridiculous energy draws to detect small missiles at enough range.
Just look at the WW2 German air radar sets to see how wide scan angles reduce range
I also have doubts in your assumption that it cannot accurately detect angles. As I have already assessed, its probably an ESA type, which means it can also calculate the angle of arrival from the phase difference of the antenna array no matter the beamwidth.
Additionally you have BAE saying this about the Typhoons HMD
The helmet works by having a number of fixed sensors around the cockpit area. As the pilot moves his head, the sensors on his helmet move in relation to the sensors on the aircraft ensuring the aircraft knows exactly where and what he is looking at.
Imagery projected onto the pilot’s visor gives, amongst other information, speed, heading and height – and crucially, it also gives the precise position of any enemy aircraft or missiles.
As you might be aware, to display the accurate position of enemy missiles, you first need to know the position of enemy missiles.

None of the Eurofighter’s MAWS antennas are located in the wing tip pods. The wing tip pods hold the ECM, ESM, and towed decoys.
Yea, my brain works not.
there arent any direct sources, sources on the working of AMIDS (or Eurofighter subsystems in general) are incredibly rare.
But there are a bunch of development notes from the manufacturer of the MAWS about components in that band, including one of GEC Marconi announcing
Additionally, to meet the increasingly demanding needs of military radar and communication systems, a new GaAs production process commenced volume production in fiscal 1997, of devices operating in the 35 to 40GHz range
The timeline fits, the manufacturer fits, and most importantly, GEC Marconi has no other products that fit military radar with such a frequency range.
Additionally in 2005 BAE Systems (who bought up GEC Marconi) showed off this, a Ka band component this time specifically for seekers/radar
Its just that they never say what its for

this is fortune-telling on coffee grounds. For such an analysis, the exact characteristics of both systems are needed. Today’s electronic warfare systems have significantly complicated radar detection, as well as satellite guidance. If we talk about the RWR Su-35, it is capable of detecting low-frequency radars.

You can also set direct keybinds for adjusting the HMD brightness

Those links are all referring to IEEE L band (1 - 2 GHz). I suspect @F0x_Hunter was talking about NATO L band (40 - 60 GHz); as in the NATO system K band is next to L band, instead of at the opposite end of the spectrum.
I have no reliable information on what radar band Eurofighter’s MAWS operates in. Various websites claim the MAWS operates at 32–38 GHz, but I’ve not seen any particularly trustworthy sources to back that up. If true though that would put the MAWS in the upper end of NATO K band, which the vast majority of RWRs in game cannot detect.
The brochure you linked gave a couple of advantages over passive systems:
- Ability to measure range to missile
- Ability to measure missile closing velocity
- Ability to accurately calculate the time to impact
- Ability to detect missiles even if their motor has burnt our and / or the missile has slowed down
I expect the all-weather detection capability is also be better than an IR / UV system.
The Brochure you linked does says that:
Low power and ECCM features protect the PVS2000 from both signal intercept and hostile jamming.
So it is possible that the MAWS is using some sort of LPI principles to at least reduce the range at which it can be detected, or reduce the likelihood of simpler RWR systems deeming it a threat that the pilot needs alerting too. However considering the the Tornado F.3 RWR was sensitive enough to detect Russian radar altimeters you are right that the MAWS can likely be detected by some RWRs, provided it operates in a frequency band covered by the RWR.
From the F.3 RWR emitters list:
