This is text from the beginning of the previous link:

The Radar Interference Tracker (RIT) is a new tool created by Ollie Ballinger that allows anyone to search for and potentially locate active military radar systems anywhere on earth.

It turns out that the Sentinal-1 commercial synthetic aperture radar (SAR) signal frequency is interfered with by C-band radars like those used by Patriot, S-300P FLAP LID & successors, 5N62 SQUARE PAIR, in fact a good number of Russian acquisition and engagement radars.
3/ ImageImageImage
Two Sentinal-1 SAR-sat passes and you get an interference pattern "X" that marks the spot of a C-band emitter.

4/ ImageImage
Also via Bellingcat:

Other military radars that operate on the same C-band frequency include naval radars such as the Japanese FCS-3, the Chinese Type-381 and the Russian S-400 surface-to-air missile system. All should be detectable when switched on and in view of Sentinel-1.

The ability of non-state actors UAV's to play SEAD games by going after Patriot C-band emitters with this tool is also a threat not to be underestimated.
6/
There are two responses to this radar interference tool tracking, one operational and one technological.

The operational one needs WW2 style close range anti-drone defense of primary ADA like the 50 cal Maxon turret was shielding 40mm & 90 mm HAA from strafing fighters.

7/ ImageImage
Smart and/or drone combat experienced SAM operators have already are already doing this. Facebook posts show Ukrainians attaching DShKM and ZU-23-2 sections to S-300 and Buk M1 batteries.

8/ Image
The other response is technological.

Putting on my 'old crow' cap, C-band ADA radars need to shift to using lower power wideband frequency hopping to push the peak power below the interference threshold of the satellites.

9/ Image
The problem with that tech solution is higher radiated power is absolutely required for C-band radar anti-ballistic missile role.

This is why the operational combined arms solution will be used more often, but the tech solution still has to happen.

10/ Image
The issue of radar interference allowing your opponents geolocate your emitters is as old as radar.

The Allies chose UK Mark III Identification Friend or Foe over the USN's Mark IV because the latter interfered with German radars. It was true when the decision was made.

11/ ImageImageImage
Unfortunately, this non-interference did not stay so for long.

When the RAF Bomber Command used its Mandrel jammers.

The Germans moved their Freya radar to higher frequencies that the Mark III IFF responded too.
12/ ImageImage
Per "British Intelligence in the Second World War" Volume 3, Part 1, the Luftwaffe exploited this radar interference such that it may have been the primary reason Bomber Command lost the Battle of Berlin during the Winter/spring of 1943-1944.

13/ Image
R.V. Jones in MOST SECRET WAR put it this way (see text photo captures):

14/ ImageImage
Further on Jones wrote:

"...the Germans’ own (Enigma) reports 9 out of the 41 aircraft lost on 2nd/3rd December against Berlin had been shot down because of their use of I.F.F., 4 out of 24 lost on Leipzig on the following night and 6 out of 26 on Berlin on 16/17th December—
15/
and these may have been due to one plotting station alone."

Similar tracking of US planes and ships was happening during the Kamikaze campaign in the Pacific because Japanese aerial radars also addressed the Mark III IFF.

Radar interference, as a tool to track enemy radars, is as old as radars.

But it's history lessons are seldom, if ever, taught. This is why 'Old Crows' say:

"It's what you think you know.
That isn't so.
Which kills you every time."

The F-35 Big/Expensive/Few Platform & Missile cult is in deep denial of this battlefield reality.

Air superiority below 2,000 feet/600 meters has been lost by crewed aircraft.

F-35's are irrelevant for the Mavic drone threat, save as a budget threat to the C-UAS procurement.
1/
The arrival of the Ukrainian Gogol-M, a 20-foot span fixed-wing aerial drone mothership, with over a 200km radius of action while carrying a payload of two 30km ranged attack drones under its wings, underlines the impact of low level airspace as a drone "avenue of approach."
2/
The Gogol-M flys low and slow, below ground based radar coverage like a helicopter.

It opens up headquarters, ground & air logistics in the operational depths to artificial intelligence aided FPV drone attacks.

This is the main example of one of the most unprofessional delusions held by the US Navalist wing of the F-35 Big/Expensive/Few platform and missile cult.

Russian fiber optic FPV's have a range of 50km - over the horizon!

1/
This means things as the Russians make these FPV's from Chinese commercial drone components in six figure and soon 7 figure (millions!) numbers.

This has huge implications for the impending Chinese invasion of Taiwan.

When China invades Taiwan, the 1st move will be occupying the small islands around Formosa (left) and making them drone, GMLRS & HQ9 SAM bases.

50 km circles around all those small islands cover almost all the invasion beaches (map right) with PLA 50km fiber optic FPV's.

It isn't just a matter of pre-2023 sniper tactics being obsolete.

Every patrolling tactic taught by the US Army Infantry and Ranger schools are obsolete when you can "just send a drone. "

1/3
Drones simply don't have ground line of sight issues like soldiers do.

Drones can see in more of the electromagnetic spectrum than humans.

And the US Army refuses to buy enough small drones (1 m +) to train their troops to survive on the drone dominated battlefield.🤢🤮

2/3
"Just send a drone" is the proper tactic for almost everything a 21st century infantryman does from patrolling, raiding enemy positions, sniping and setting up forward observation posts.

Please note that Iran _ISN'T_ shooting down IDF drones over Tehran⬇️

There are technological reasons for that.

1/2
The odds are heavily in favor of the IDF having parked Hermes drones with "Gorgon Stare" technology over Tehran to hunt Iranian senior government officials.

2/2 Image
P.S.

This is the wiki on Gorgon Stare technology.

The following photo captures from WW2 bomb damage analysis documents are to calibrate people's eyes as to what to expect from the Fordow strike.

The MOP crater is going to be something called a "Camouflet" because the MOP will dig so deep before exploding.

1/6 Image
The problem with this US strike is the rock density in the Fordow area may be too much for the GBU-57/B MOP (See Grok below)

Unless there is really good intelligence showing a weakness in Fordow or...

2/6

...this MOP strike had several bombs with the same aim point and a timer setting for simultaneous detonation. Good results will be difficult.

WW2 testing showed hard crystallized limestone was a pain for semi-armor piercing bombs dropped from 16,000 feet to penetrate.

Well, it wasn't a TACO moment.

This US strike on the Iranian nuclear program was paddy cake.

The Iranian smart move here is screaming a lot, doing little and waiting for a Democratic US President to build nukes.

1/2 Image
The dumbest of dumb moves by the Iranians would be laying sea mines in the Strait of Hormuz.

That was what set off Operation Praying Mantis in the late 1980's which sank 1/2 of Iran's navy in a day.

If the Iranians choose doing something dumb...

...US has positioned aerial assets in the Mid-East that are sufficient for a modestly large aerial bombardment effort for ~100+ tactical fighters⬇️
