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."

Fearless prediction: N. Ireland will be 90%(+) migrant free in 3 months.

It is now clear to me that what we are seeing in N. Ireland is a sectarian pogrom.

One which will in 3 months be utterly successful in driving out 90%(+)...

...of the migrants the UK government has placed there. Then Liverpool will be next.

The UK government utterly failed to stop mutual Catholic/Protestant pogroms in the late 1960's early 1970's troubles.  When half N. Irish population was nominally...

Currently the vast majority of white middle and working classes in Northern Ireland are on-side with the anti-migrant pogrom...

The problem with this analysis is it leaves out the drone & power projection capabilities of the PLA and Taiwan's highly vulnerable off shore islands.

PLA & PLAN parachute, heliborne & marine landing forces can take all of those small islands as a coup de main for drone, SAM & MLRS bases.

The ability of Taiwan to operate it's HIMARS is tied directly to it's ability to deny China drone air superiority inside Taiwanese air space.

China can throw 1 million OWA drones to suppress Taiwanese air defenses to take those off shore islands.

The PLA holding the Pescadores, Green and Orchard islands as launch platforms for HQ-9 SAM's, heavy MLRS rockets and Hornet class truck hunting drones means it can overwatch & reduce Taiwanese beach defenses, all while denying air space to ROCAF fighters.

Russia faces a logistical dilemma in occupied Ukraine for which it has no good solutions.

Crimea is a de facto island fed by road and rail bridges Ukraine can now destroy at will, and Russia cannot stop.

And Ukraine is destroying those bridges.

1/ Image
Russia's air defense has suffered a nearly complete "Lanchester Square Collapse" proximate with the Ukrainian mass deployment of both 150 km range AI truck hunting drones and bridge busting FP-2 OWA drones.

Any route Russian trucks take to Crimea will result in parking lots near replacement pontoon bridging for both those kinds of drones to exploit.

"Trucks that mass together...die together.

Saving Space Access From Kessler Syndrome

Elon Musk’s plan for XAI satellite data centers, and all use of space for any purpose, faces inevitable collapse until a solution emerges for the problem of Kessler Syndrome (see Wikipedia). 🧵

1/
This will occur when enough collisions of small orbital debris pieces from old dead satellites hits the steadily increasing number of new satellites until the whole thing spirals into mass collisions.

Kessler Syndrome computes that this will destroy all existing

...communications, navigation, observation and research satellites in low/medium orbit, and prevent all further satellites launched, for 40+ years, until enough pieces fall out of orbit into the Earth’s atmosphere.

Do you remember all the 2023 US Navalist accounts o X that screamed at @johnkonrad and I about pointing out the containerized anti-ship OWA drone threat to the US fleet.

Welcome to 2026 Ukrainian anti-ship OWA drone threat, you US Navalist yo-yo's. ⬇️

"Operation Spiderweb with Chinese characteristics" is coming for you all, and we have the receipts.

We need a whole lot of air defense guns everywhere to stop drones that you guys still refuse to fund.

For fun and reference of guns versus missile air defense, this YouTube test scenario pits 100 Shahed-136 one-way attack drones against the historic US Navy Task Force 38.1 from 1944.

Just...no. The 8th AF fudged its accuracy numbers.

It excluded "gross error" bombing runs beyond 3,000 feet from the target. Which were above 10% of all 1944 bombing runs.

Below, the inner circle is what a 1944 1,000 foot (304m) CEP in WW2 looked like when dropped from 400(+) four engine heavy bombers.

Using this document:

THE UNITED STATES STRATEGIC BOMBING SURVEY
Bombing Accuracy, USAAF Heavy and Medium Bombers in the ETO
MILITARY ANALYSIS DIVISION
First Edition 3 November 1945
Second Edition January 1947

You find both mission failures & gross errors were "excluded data"

And that both increased altitude and the number of combat boxes involved made CEP worse.
