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.

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—

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 following is evaluation is based on a number of professional discussions:

This CRPA found in a shot down jet Shaheed is reported to be Russian built. This is highly doubtful as the design and construction style looks far too professional for Russian industry.

1/
Bluntly - Russians tend towards cheapskate up-front capital manufacturing solutions.

The upshot is injection molded and die cast components are not a common feature in Russian designs as tooling for manufacturing designs is expensive up front,

2/
...even if the mass production unit costs are lower.

In addition, Western style SMA RF connectors are not a feature of the Soviet technology base.

Nor is the RF coax with a transparent jacket.

Let us be clear what has happened here.

Ukraine has a drone armed merchant raider lose in the Mediterranean hunting Russian shadow tankers.

Upshot: There will be more elsewhere on the world's oceans in the near future effecting maritime trade.

2025 Merchant Armed Raider 🧵

@grok answered the following questions for me:

" Please summarize the pre-World War 1 to 1942 career of merchant armed raiders and compare that data to Ukraine's recent drone attack in the Mediterranean with a drone armed commercial vessel."

This is @grok's final summary:

"In essence, Ukraine's approach modernizes the raider concept—swapping guns for drones and merchant disguises for stealthy launches— but lacks the historical volume due to the conflict's constraints.

US Ground force flag ranks deny this 2025 reality 🤡⬇️

"The Ukraine war has exposed a large and increasing gap between Western reconnaissance doctrine and modern conventional battlefield reality.
1/3
In Donetsk, reconnaissance operators face constant drone surveillance, electromagnetic degradation, and hyper-local combat conditions that invalidate long-held assumptions about stealth and standoff intelligence, surveillance, and reconnaissance (ISR).

2/3
This article contends that NATO must, with urgency, reform its reconnaissance doctrine, training, and force structure to survive and efficiently operate in a drone-saturated battlefield."

I said this about the US Navy in 2023 (⬇️)

....and the institutional failures on display in the USS Truman CVBG Red Sea deployment proved me correct in 2025.

1/2
Every competent USN surface officer knows in their gut an anti-aircraft cruiser should not be operating with downed identification friend or foe (IFF) and Link-16 data link with no E-2 Hawkeye AEW support.

Those officers know in their guts that radar skin paints alone from their ship's SPY-1 will be borderline for high tempo engagements...

...but this is not the first time this kind of problem occurred:

Just...listen...to this video clip with your eyes closed.

The predominant sound isn't artillery.
It isn't assault rifles.

It is the scream of drone rotors coming close, punctuated with the explosion of the drone upon impact.

1/3
That sound drama isn't World War One or any "medium intensity" conflict since 1918.

It is the sound of how 21st century Peer-to-Peer conflict is fought.

A conflict Western ground militaries are obsolescent in equipment to face.

2/3
That Russo-Ukraine War video is a soundscape US Army National Training Centers are too obsolete/incapable of replicating, because US Army flag ranks are allergic to training with high densities of small/cheap/many FPV drones.

WW2 is calling again with Ukraine developing Drone version of SHORAN.

1/
SHORAN was a WW2 blind bombing system using two radio stations and an electromechanical computer.

In 1938 an RCA engineer named Stuart William Seeley, while attempting to remove "ghost" signals from an experimental television system, discovered he could measure distances
2/ Image
...by time differences in radio reception.

Instead of building a radar unit with this discovery, he proposed using this technique for precision ground-based radio beacon navigation bombing aid.
