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/
Two Sentinal-1 SAR-sat passes and you get an interference pattern "X" that marks the spot of a C-band emitter.
4/
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. 5/
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/
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/
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/
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.

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/
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/
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.

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

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."
and in September, 1,202 KIA and 649 WIA, i.e. 1.85:1.
These numbers strongly exceed any previous campaigns dating back to the Crimean War, and do not include non-combat deaths due to disease or exposure."

Late 20th Century combat saw one dead for every four wounded.
Russia is suffering between one and 3/4 to one to something like one and 4/5ths to one killed to wounded at Povrovsk.
Gosh, remember all those 2023 US Navalist accounts that denied - DENIED, I tell you - that drones from containerships would ever, ever, be a threat and that I personally was delusional for saying so publicly.
One in every five US Naval vessels are defenseless to Chinese drones, surprise launched from Chinese merchant & fishing vessels, because the
every CNO since 1989 didn't want USN logistical officers to get a captaincy and compete for flag ranks.
Instead of dealing with reality, the USN flags send out minions on X to say "de-lu-lu" things like this⬇️
Because the USN Flags from the Aviation, Surface and Sub communities don't want to have logistical officers get flag ranks and spotlight their professional delusions🤮🤮 3/3
The missile is currently active aboard Gerald R. Ford-class aircraft carriers, Nimitz-class aircraft carriers, Wasp-class amphibious assault ships, America-class amphibious assault ships, San Antonio-class amphibious transport dock ships,

Whidbey Island-class dock landing ships, Harpers Ferry-class dock landing ships, and littoral combat ships (LCS).[6]"
This was a US Navy procurement disaster in the age of drones.

"Western Experts" on X who claim drones are a "Ukraine War unique fad" are complete fools⬇️
"Among the sensitive targets of September 2025:
• 1,895 ‼️ enemy wings of the Orlan, Zala, SuperCam, Lancet types, Molniya kamikaze wing, Shahed, Gerbera.
• 455 enemy pilot launch points and 738 crew antenna units.
• 150 mobile EW systems and 9 self-propelled EW systems.
• 2,124 self-propelled vehicles (armor, logistics, rocket artillery, auto-moto vehicles, MLRS).
2/3
• 394 cannons and howitzers.
• and much more weaponry, assets, depots, shelters, etc."
The #1 counter-battery weapon on the 2025 battlefield isn't ballistic or rocket artillery.
The Russian Legioner armored vehicle is an interesting reinvention of the 1940's Red Army BTR-152 or US M3 Scout car.
It says a great deal about the defense industrial infrastructure limitations of the Russian Federation.
1/
The three 6x6 BTR-152 photos and drawings and one 4x4 M3 scout car photo will give you an idea of what is available to the 2025 Russian defense industrial base.
